Yesterday, I noticed that one of my girls looked like she had injured her neck. She is one that is very skittish around us, so the only time I could inspect her is at night. I couldn’t see any broken skin, but the back of her neck and onto her back, she’s missing feathers but still has the barbs in there. She’s 8 months old, so I’ve never been through a molt, but am assuming the barbs come out too. My best guess is bullying, although I haven’t seen it, or maybe from a predator? I’d appreciate any experienced chicken parenting advice!
