Just a few days ago my 7 hens and banty rooster stopped going in the coop at night... They go to the door but dont go in. The coop sits up about 3ft and there is a ladder/ramp for them and that is where they have been sleeping. They have a yard about 30x30 all day and a 30x6 run built off the coop. I got lights so they would stay up later on these short days and keep egg production up. They were staying out till 530 in early october before the lights, then early november they were up till 830-9 with lights. then two weeks ago jumped to around 11 and now I dont know when they go to bed.
