Hi we have four girls 2 Jersey Giants, 1 Dominic, 1 Easter Egger. They are 15 weeks old and the faces are getting a bit red. We are transitioning them from medicated chick feed to layer feed 50/50 this week. My concern is, we have three nesting boxes in the coop each with some hay and a golf ball (hopefully to teach them), however, they seem to be perching on the edge of the boxes and sleeping/pooping there at night. They have a perch in the coop it is a bit higher than the nesting boxes, but they do not use it. Should I be worried? Anything I should do? Thanks so much for the help.
