We Compared 6 PVC Chicken Feeder Kits on Hole Size

Why the ZenxyHoC 8-Port wins this category

It is the most complete kit here, and it is the only one that admits the build has a rule.

Every port ships with a rainproof cover, a rubber gasket and a night plug. That last item is the one that separates it. A cover is a hood over the cup. A plug seals the opening shut, so a closed port at dusk is genuinely closed rather than merely shaded.

The hole size is stated plainly at 3.15 in, so you can buy the saw before the box arrives instead of after. And the maker tells you to leave 3 in between the port and the bucket bottom, which no other listing in this guide bothers to say. That gap is what stops the port body fouling the base and what leaves a sensible reserve of feed underneath.

At $24.99 for eight, the cost works out at $3.12 a port.

Living with the ZenxyHoC 8-Port

The feed opening extends downward rather than sitting flush, which is the shape that does the work. A hen has to reach in and lift feed out rather than sweep it sideways, so less ends up on the ground.

Expect to spread the eight ports over more than one container. A 5 gallon bucket wall is only about 11 in across, and four holes is already a lot of missing plastic. Two buckets with four ports each, or three containers with two or three, uses the kit properly and gives your flock feed in more than one place.

Gravity feeders also have a habit that surprises first time builders. Feed only flows while it sits above the port, so the base of the container never empties. Tip it out every few weeks so the bottom layer does not sit damp.

Where the ZenxyHoC 8-Port falls short

The listing does not confirm a hole saw is included. Four other kits in this guide say plainly that one is in the box. Assume you need to buy a 3.15 in saw and treat the real cost as higher than the sticker.

The 3.15 in cut also rules out 4 in pipe. That pipe is about 4.5 in across the outside, so the hole takes out nearly the whole wall and leaves a curved sliver on each side with no flat ring for the gasket. Buckets, bins and troughs are fine. Narrow round pipe is not.

The night plugs are only as good as the routine around them. Eight ports means eight plugs to close at dusk and eight to open in the morning. Miss an evening and the plugs have done nothing at all.

Why the LPLEA 20-Pack wins this category

Because it changes the unit of the decision. Every other kit here sells you enough ports for one container. This one sells you enough for a small setup.

Twenty ports for $34.99 works out at $1.75 each. That is the lowest cost per port in this guide by a wide margin, and it comes with 20 rubber rings and a hole saw, so nothing else needs buying before you can start.

The $34.99 is also the highest pack price on this page, which is exactly why the arithmetic matters. Judged on the sticker it looks like the expensive option. Judged on what a port costs, it is the value buy, and the gap only closes if you have nowhere to put the ports.

Living with the LPLEA 20-Pack

The hole size is stated at 3.15 in, which is the same cut as the ZenxyHoC and GSHWXD kits. A 5 gallon bucket takes it happily. A square storage bin takes it better, because a flat wall gives the rubber ring a clean flat ring of plastic to seal against.

The maker suggests mounting the container 6 to 10 in off the ground, and that is worth following. Cups at back height keep bedding out and stop birds scratching feed back onto the floor.

Fitting 20 ports is an afternoon rather than an hour. Do them in batches, fill each container and watch for 10 minutes before you move on, because a ring that has slipped is far easier to spot on a full bucket than on a mounted one.

Where the LPLEA 20-Pack falls short

Most backyard keepers do not need 20 ports. One bucket wants two to four. If you have one container, you are buying the highest pack price here and using a fifth of it.

The lid is described as blocking rodents as well as rain. Take that carefully. A closed lid does obstruct a rat. An open one does nothing at all, and the lid does not close itself, so the claim really describes a nightly chore rather than a feature.

The feed saving figures, 15 to 30% from the design and another 5 to 10% from the lid, come with no test, no method and no comparison feeder. The mechanism is plausible. The numbers are marketing.

And like every 3.15 in kit here, this one is not a 4 in pipe solution. That pipe is about 4.5 in across the outside, so the cut leaves no flat surface for the ring.

Why the GSHWXD 4-Port suits one bucket

Because four is the number a 5 gallon bucket can actually take.

The wall of a 5 gallon bucket is roughly 11 in across. Each port here needs a 3.15 in hole, stated helpfully as 80 mm as well, so four cuts already remove a serious amount of plastic. Any more and the wall starts to flex under a full load, which is how gasket seals begin to weep.

So a 4 port kit is not a compromise on a single bucket. It is the correct size, and buying eight or 20 ports for one container just leaves the rest in a drawer.

The hole saw and four rubber rings are confirmed in the box, so $16.99 is the whole spend rather than the start of it.

Living with the GSHWXD 4-Port

The maker says the port body is 15 to 20 g heavier than a standard port. That is a small figure written down plainly, which is more than most listings manage, and thicker plastic at the flange is where these things fail first when a bird stands on an open cover.

The inlet extends 0.8 in downward with a forward and backward tilt. In practice that means a hen has to reach down and lift feed rather than sweep it out sideways, so less lands on the ground. GSHWXD does not attach a percentage to that, which is a point in its favour next to the kits that do.

Mount the ports a few inches up from the bucket floor and raise the whole container to back height. Feed only flows while it sits above the port, so the base never empties and the reserve underneath needs tipping out every few weeks.

Where the GSHWXD 4-Port falls short

Per port it is the costliest of the five feed-only kits in this guide at $4.25, so as soon as you are fitting a second or third container the arithmetic goes against it. Twenty ports elsewhere on this page work out at $1.75 each.

Four ports also sets a ceiling on the flock at one station. Plan on one port for every two or three birds and this feeds eight to 12, which suits most backyard flocks and leaves nothing spare for a second feeding point at the far end of a long run.

And the 3.15 in hole is a bucket and bin cut, not a pipe cut. Four inch SCH40 pipe is about 4.5 in across the outside, so this hole takes out nearly the whole wall and leaves the rubber ring nothing flat to press against.

Why the DSTANA 6-Port suits a narrower container

Because it asks for less of your wall than anything else here.

Three of the kits in this guide need a 3.15 in hole. The DSTANA needs 3 in. That difference sounds trivial written down, and on a wide flat bin it is. On a narrower barrel, a trough side or a small square container it is the difference between a clean flat ring of plastic around the hole and a cut that runs out of material at the edges.

A port flange seals against flat plastic. Leave more of it behind and the seal holds better, so on any container where you were already worried about the cut, the smaller saw is the safer choice.

Six ports, six lids and a hole saw come in the box for $21.59, which is $3.60 a port.

Living with the DSTANA 6-Port

The internal height is raised 0.6 in, which is the recessed lip that makes a hen reach into the cup rather than sweep feed out of it. DSTANA attaches a 30% less spillage figure to that design and cites nothing to support it, so treat the shape as sensible and the number as a claim.

Each port has a lid that works as a rain cover and as a night cover. As with every kit here, that only counts if the lids are closed at dusk. A lid left open all night is a feeding station for whatever visits the run.

Six ports splits well across two containers at three each, which puts feed at two points in the run and keeps each bucket wall intact.

Where the DSTANA 6-Port falls short

The species restriction is the big one. The maker states it is not suitable for turkeys, chicks or ducks. If you run a mixed flock, that is not a footnote, it is a second feeder you have to buy, because a duck cannot bill feed out of a recessed port and a chick cannot reach it.

The material is simply not stated. Every other listing here at least says plastic, PP or BPA-free, and this one says nothing, so you cannot check what you are putting feed through until the box is open.

The box contents are thin in one more way. It is listed as 6 ports, 6 lids and a hole saw, with no rubber rings, where the ZenxyHoC, LPLEA, GSHWXD, Essilnn and Poutilor kits all name a gasket or sealing ring. The flange then presses straight onto the cut plastic, so a saw that wanders even slightly leaves a path for feed dust and rain to work in behind the port.

A 3 in hole is smaller than the rest, but it is still not small enough for 4 in SCH40 pipe at about 4.5 in across the outside. The curved sliver left on each side gives the flange nothing flat to seal against, so this is a bucket, bin and trough kit like the others.

Why the Essilnn Feed + Water covers both jobs

It is the only kit in this guide that does more than feed.

Six feed ports with rain hoods and gaskets come alongside six water cups, so one order fits out a feed bucket and a water bucket at the same time. If you are starting a bucket based setup from nothing, that is a real saving of effort, and 12 fittings for $28.49 works out at $2.37 each.

The water cups run on a 1/8 in NPT thread, which matters more than it sounds. NPT is a standard, so replacement cups and fittings are easy to buy from anyone, and you are not tied to this seller when a cup eventually sticks open.

The 3.8 in cup opening is wide, which suits heavily wattled hens that struggle with a narrow valve.

Living with the Essilnn Feed + Water

Cups and ports need different treatment once they are up. A feed port stays clean for weeks. An open water cup collects shavings, dust and droppings, so plan on rinsing it every few days rather than every few weeks.

Keep the two buckets apart in the run as well. Water splashed onto spilled feed is how you get a mouldy patch under the feeder, and a couple of feet of separation solves it.

The feed ports use a rain hood and a waterproof gasket. As always, a hood keeps rain out of the cup and does nothing about a rat at night, so the routine of covering the ports at dusk still applies.

Where the Essilnn Feed + Water falls short

The missing hole size is the real problem. Four other kits in this guide print a figure, either 3.15 in or 3 in, and this one prints nothing. That is the one number you need before you can cut, and without it you cannot even order a saw in advance. The listing also never confirms a saw is in the box.

The material is not stated either, for the ports or the cups. Given that both carry feed and drinking water, that is a gap worth noticing.

The waste claim of 5 to 30% is so wide it carries no information. A range that broad, with no test and no comparison feeder behind it, is a marketing line rather than a specification.

Why the Poutilor 4-Port is the budget pick

At $15.80 it is the lowest price in this guide, and unlike the winner it confirms a hole saw in the box.

That combination matters more than a few dollars usually would. With most of these kits the sticker is only part of the spend, because a 3.15 in hole saw is a separate purchase. Here the saw, the covers and a rubber gasket all ship together, so $15.80 really is what the project costs.

Four ports is also the right count for one 5 gallon bucket. The wall is about 11 in across, and four holes is roughly as much material as it can lose and still stay rigid when full. Buy a bigger kit for one bucket and most of it sits in a drawer.

The body is BPA-free plastic, which two other listings in this guide never state at all.

Living with the Poutilor 4-Port

The feed opening is extended rather than flush, so a hen reaches into the cup instead of sweeping feed sideways out of it. Poutilor puts 15 to 30% on that, with no test named and no comparison feeder, so take the shape seriously and the percentage lightly.

Each port has a rain cover and a lid plus a gasket for sealing. The lid keeps water out. It is not a rodent lid unless you close it every evening, which is a habit rather than a feature.

Mount the ports a few inches up from the bucket floor and stand the finished bucket at back height. Feed only flows while it sits above the port, so a few inches of feed always stays trapped at the bottom. That is normal, and it is worth tipping out every few weeks so it does not go mouldy.

Where the Poutilor 4-Port falls short

The hole size is not stated anywhere. That is the single number this whole category turns on, and its absence is the reason the lowest price here does not take the top spot. The saw in the box will match the port, but you cannot plan the build, check the container or order a spare saw without measuring the collar yourself.

That also makes it impossible to say in advance whether it suits a narrower container. The DSTANA kit prints 3 in and three others print 3.15 in, so you can judge those against your bucket before ordering. Here you cut and hope.

Four ports feeds roughly eight to 12 birds at one point in the run, so a larger flock or a long run needs a second container and a second kit.
