As a matter of background, all 9 hens and 2 roosters have been brought up together and are 7-months old. I have hens in one coop (Molly my Delaware and Snowtop one of my barred rocks), and the rest of the hens in the other coop (Stella & Henrietta - the Australorps, the other barred rock, Abby, my Speckled Sussex, Lucy and the three silkies, Beyonce, Nugget and Chicken Little). Both coops are in the same run. The problem is in the coop of six. Chicken Little has always been at the bottom of the pecking order, but until recently she has been able to roost at night if I put her in the right place. Of late, all of the hens are pecking at her and they can all reach her - or if they can't, they go out of their way to do so. I moved her to the coop of two, but she just sits at the door and pecks at the door - she did it for hours before I moved her back. She sleeps on the floor of the coop now. I tried to move her to a nesting box, but she goes back to the floor. I can't isolate the bullies - they are all doing it. I am thinking I should give the silkies a coop of their own. Help please, I feel so bad for her.
