I have 3, 2 year old hens of different breeds. I decided to add two more girls this year. I raised them in the house until they were feather and then put them in the coop separated from the other girls for 2 or 3 weeks and slowly let them with the others. Over the weekend, I let them all be together. BIG mistake, they scalped one of my baby girls. For the first time in raising chickens, I had to cull. I have my other girl, who is now separated in the coop from the others. My question is, will she ever be part of the flock. She wants nothing to do with the older hens and I don't blame her.
