I have about a dozen bantam cochin"pet" chickens, hens and one rooster. I had one of the hens sitting on a nest of call duck eggs for me and just returned her to the chicken run. The other chickens beat her ruthlessly until her head is bleeding and both her eyes swell up so she can't see to defend herself anymore. I know there is going to be some trouble, but she seemed half dead the last time I took her out. I returned another hen to the run after sitting on eggs without so much fuss, but this one they seem intent on killing. She was always mid-high pecking order before she sat on the duck eggs, and was one of the nicer looking hens since she wasn't missing any head feathers from getting pecked by the other chickens. She is also at least half the wait of the other chickens since she didn't eat very well while sitting on the eggs so she has trouble fighting back although she tries when she can still see. I do have two Ameracauna hens as well, and they really lay the smack on her since they are so huge. It is them and about 3 of the other hens and the rooster that are doing the worst damage and really stalk and chase her constantly, but everyone gets a peck in when they can. Does anyone have advice on how to make this transition go more smoothly? I already put her in a pen right next to the run so they could see her for about a week and get used to her being "around". I also returned her in the evening this time so she could roost with them at night instead of getting beat right away but they are at it again this morning like they did a week ago. Please help!
