I have five Marian pullets that have integrated into the chicken run and are very happy. None of the hens seem to care. I have an automatic door and I go and check after dark and the hens have gone in but the pullets are in a corner outside. I then put them in the coop for the night. I have seen them go in and out of the coop in the day, why won’t they go in at night? What can I do?
