At night my 2 roosters and 4 hens normally will go into their shelter around dusk. Lately I have one hen that isnt with the other when I go to shut the doors. Lately she is coward in the corner at the top of my garage steps. I have to pick her up and bring her to her shelter. When i open their door in the morning always in the corner closest to the door and aways the last one out. Is she being bullied by the others? I Dont notice that shes being picked on.
