I live in NY. Long Island NY. I have a small chicken coop. I have the coop that I bought on Ebay enclosed with a huge run. So the coop is within the run area. It is completely enclosed by chicken wire, roof and everything. The problem is that all of a sudden my chickens who have just begun to lay eggs ( they aren't laying in the nest boxes but in the chicken coop itself on the floor) Now out of the blue they have begun to sleep on the roof of the chicken coop. I have read online that others have had the same problem. The others were concerned due to the chickens being eaten by racoons or foxes. That isn't an issue for me as the coop is enclosed. But what about the fact that they are sleeping out in the open in the elements? Last night it snowed and they were sleeping on the roof. A few times we have put them back in to the coop but they still like to sleep on top of the roof. Today i put on some metal sheeting so that they can't grip the roof and i hope that they are going to go back to sleeping in the coop. Any advice? is it safe for them to sleep out in the open? Wouldn't it be an issue of nature knowing what to do and the chickens would be sleeping outside only if they can handle it and then sleep inside the coop when it gets too cold for them or do they need help?
