I have a possible problem. I noticed that my chickens will literally follow their guard dog around when he's ready to poop. They clean it up in no time, and it's like the highlight of their day. We just started this batch for egglaying, and they haven't started laying yet (maybe soon), and I wanted to know of any dangers. We also wanted to kill off some of the roosters soon for eating. Is this safe? Is there a way to discourage them from eating the dog poop? They free range of course, but are they not getting enough to eat?
