I recently added a rooster and hen to my existing flock of three hens. Currently, only the rooster and two of the older hens will roost (sleep) inside of their coop. The other two (the new hen and one old hen) roost in trees outside of the coop and their fenced run. Kind of a problem, since they haven't figured out how to get back into the run where they are protected and have access to food, water, etc. Any suggestions for how to get the two wayward hens back to roosting in the coop again? I have been going out every night and carrying them back to the coop and then locking it up till morning, but the next night they are back in their roosting trees again. thanks for any advice!
