I meant to make my PVC feeder out of 3" tube, but came home with 4" by mistake. Glad I did. My rooster has no problem at all.I have been fighting this war myself. Ive been trying to perfect a no spill feeder.
I tried the one with the 3" PVC 90, but my rooster couldn't get his head in. His crown stopped him. I figured hunger would get the best of him, it didn't. He refused, he was not eating, so I changed my approach.
Im trying to get rid all of their food.
