If you wanted a lot from our chicken feeder it had to be easy to fill, hard to spill, safe from non-chicken life forms, weather resistant, easy to make, and inexpensive. We tried a number of other designs that worked to varying degrees, but this was the only one that did all we asked it to. Enjoy!
There are lots of PVC chicken feeders, and several folks have gone with a design very similar to this one. But I haven’t seen the extra three-inch piece added to the Y connector: without that small extension the chickens managed to spill quite a lot of food, but that three-inch piece cut spillage to almost zero!
We tried a 180-degree elbow with the edge cut off: the birds were able to eat just fine but they spilled quite a lot, and closing the pipe for waterproofing and rodent-proofing would have required additional engineering. We considered quite a few other variations, but they all had drawbacks; mostly related to spillage and security.
At first the bottom part connected to the “Y” was only three inches long and the birds didn’t like that much, so we set it up on a brick and the chickens seemed to like the altitude better, so the final version uses a six-inch length of pipe to place the food where the chickens can easily reach it.
Another way to go (and in response to some reader comments): if you add some kind of plug right at the bottom of the Y, the birds would be able to reach all the food. It will take you more than 3 minutes to assemble, but it would be more efficient. Of course, it’s best to use plastic or something else that can be thoroughly cleaned.
