This is my second shot at this feeder the chickens did not like the first one and it was ugly. So here are the lessons learned.
1. Melt the holes in the tub. If you just cut them in the plastic has a tendency to crack. Also too big is ok, too small and the plastic will crack. You can fill the gaps with a little hot glue if the pvc is loose.
2. Cut a 4" 90 in half do not use entire 90 or 2 street 45’s. This assumes your chickens are as picky as myn are.
3. Cut card board to slope the bottom. This is optional but really helps if the feed gets low.
This one works well and cuts down on lost feed dramatically.
