Bought 2 (around 3 month old) chickens to add to our flock after losing two of our girls. They are currently in our smaller coop while they adjust. Problem is, they came from a coop full of chickens and I doubt they ever had roosting room. They won't roost on the roosting bars in the coop. They lay on the house floor which normally wouldn't bother me but they lay right at the edge and stick their heads out into the night air. They are protected by wire. Is there a way to teach them to roost on the bars?
