My niece decided she didn't want her 4 chickens anymore so we took them in. One just started laying about a week ago but here's the problem...All 4 sleep & poop in their nesting boxes. The one that is laying does lay them in the nesting box but it's got poop all over the egg every time from them pooping there. I clean it out EVERY DAY & put a small amount of hay in the nesting boxes. They kick the hay out EVERY TIME!!!!!!!! They have 2 roosting bars. I could care less if they sleep in there but is there anything I can do to stop the POOPING??? I am beyond frustrated lol please help!!!!!!!!!
