My chickens usually go back to their coop in the evening. However, last night they roosted in a tree above their coop. Tonight, 5 of 6 were on the roof of their coop. I put them all inside. But, is this going to be a problem? Should I let them stay out over night?...and yes we have predators (coyotes and raccoons). I keep their food and water in the coop and usually let them out at 6 am and make sure they are secure in the evenings. Mainly concerned with where they will lay their eggs since they are only 4 months. Just curious. Thanks.
