Noticing there was quite a pile under the roost, I planned on gettin in there today, and cleaning it out. We had some snow, and some cold, and those chickens were reluctant to get outside. I fed them plenty inside the coop, and decided to kick them outside when it got sunny. My oh my, went in to clean, and poof! the pile was missing! Now, there's been no one in there but them....any one have any experience with this possibility?????
