Recently, I have been worried about one of my chicken's attitude, she is a barred rock that lives with 3 other sex links. My BR is slightly younger than the other three sex links, and she has been acting odd lately. We originally bought her with another BR, but she passed awhile ago (4 months ago). Winter, my BR, has lately been shifting away from the others and is at the bottom of the pecking order. For example, sometimes she sleeps on a different perch from the others or forges alone. She also hides in our bag of flakes for a decent amount of time and makes quiet awkward sounds I usually don't hear from the others. Her tail is still up though, and her poop looks normal, but she sometimes gets pecked while eating. Is it depression or I'm I just paranoid? How can I fix it?
From what I've always noticed, they partner up with their own breeds, even as broodmates. Like for instance, among others, I have 6 BRs and only one sex link, and my sex link is always by herself and the BRs split into two flocks of " 3 musketeers". Peaches(the sex link) spends almost all day following me, or foraging by herself. She gets pecked by the BRs, but everybody does. The BRs are the biggest chunk of one breed, and they're like a gang
Keep an eye on her just for health reasons, but its normal and ok for a hen to decide to be by herself
I agree, especially if the new hen is the same age or younger, and the same breed or at least a less aggressive breed.
They could even be housed together for a while to create a bond. While members of the same breed may stick together, birds that were raised together or otherwise become friends often bond quite well.
