My chickens are approaching 17wks. I have 7 pullets and 1 cockeral. At first I didn't cover the nesting boxes and they all slept up in them. About a month ago I finally covered them up so they couldn't get in them and they either slept on the floor or the roost bar. I removed the cover over the weekend and noticed that they are sleeping in the boxes again. It still may be a while before they lay but you never know if they may lay early. Should I put another roost bar up a little higher? Cover the nest boxes back up? I bought some wooden eggs today to put in the boxes. Any ideas of what I could do?
