On Friday we put pinless peepers on my 56 hens. Saturday I noticed they didn't eat as much as normal. Today I noticed they barely ate at all. I normally fill their feeders when I check on them for the last time in the early evening, and close them in for the night. When I go out in the morning and open up the coop the feeders are almost empty. By feeding time they are always empty. Today ( Sunday) at feeding time the feeders were nearly full. So I put a couple of small piles on the ground and they ate like crazy. I have the more commom hanging feeders. Are they going to get used to eating out of them or do I need to change the type of feeder?
