I have one pullet that refuses to go into the coop with the rest of the chickens at night. Instead she ends up finding a roost somewhere in the feed and tool shed which is an open air lean to. I have to end up going out every night and put her into the coop. I am worreid if I have to travel and be away once it warms up that she will become something's dinner. Anyone have any ideas on how I can break of it? I've already tried to do away with the spots she has roosted in but she always seems to find another spot to roost.
