Not really sure what to do regarding my chickens. So they are all roughly 21-22wks old. They will NOT roost at night, instead they all huddle into the corner. I have placed them on the roost since they were little and yet they just wont do it. They even have a roost in the run an they don't really care for that one either. Now a few of my girls are starting to lay and they are laying in the corners of the coop. They wont hop up into the nest box. Should I lower the nest box or put like a milk crate on the floor or what? Will they ever roost?
