My first attempt at a custom chicken feeder didn’t work so well — the feed tended to not make it far enough past the 90° elbow to reach the holes where the chicks eat.

So I modified it to use a 45° connector instead (which Jenn kindly picked up on the way home from work). I didn’t want it quite that steep, so I joined the parts with some duct tape:

The new angle works much better; the food freely flows down to fill the tube, but doesn’t overflow:

Having four hole heights means chickens of all sizes can reach the food without a platform, too.

Hopefully this will work reliably; time will tell.
