We purchased two hens at auction yesterday, both from the same auction group. One of our hens, a Barnevelder, is doing fine. But the other, a dark Brahma, isn't. She came out of her shipping box, pecked me, then ran off to go eat. Immediately, she started picking fights with the other birds and in turn they defended themselves. The Brahma quickly went into a cage and was kept separate over night from the rest of our flock, in our coop. We decided that we'd butcher her; we weren't keeping a mean bird. Today, I was trying to get her out of the cage to check her out and see if, besides having plucked feathers, she was healthy. She quickly escaped and ran out to get some water and food (she'd knocked over her water and ate all of the food we'd given her), then calmly walked off on her own. We decided to just watch her and see if she'd fight with the other birds, and she really didn't. If anything, the other birds decided to pick on her. We've come to the conclusion that she was probably picked on so badly by the other birds that she was submissive to our layer girls and even stayed away from our silkies. The aggression seemed to stem from the stress of being kept in a cage with the other birds that were picking on her and the stress of the auction and shipping process. Later tonight, we had friends over and they decided to check out our chickens, as we're babysitting some of their hens. Their son went into the coop and claimed that the Dark Brahma was picking on the Light Brahma (probably just normal pecking order stuff). I scooped her up just in case, and just held her for a little while as my mom set up her cage for the night. She actually let me hold her, laid on my lap, and I just sat, petting her. I didn't even have to hold her. She turned and stuck her head under my arm and fell asleep. Like, we thought this bird was going to be mean and aggressive not only our birds, but us as well. But in fact she quietly let me handle her and she didn't display any aggressive behavior at all. Like I said, she'd obviously been picked on by other birds and my girls just don't seem to like her and even were even attacking her without warning. She's been sweet to us and just doing normal, pecking-order type behavior while she was with our girls today, but the other birds are not taking to her well and have been absolutely awful. Our Cuckoo Maran pullet, as the Dark Brahma was laying down for the night, jumped on the poor bird's back and just started attacking her, scratching and pulling at her feathers and such. We really want to keep this bird, but we don't know how to deal with our flock's aggressiveness towards her. Any advice or ideas on how to integrate this pretty lady are greatly appreciated; we'd love for her to have a good life like our other free-range girls, not living in a cage.
