This is what she looked like when she's younger. I was just told she was hatchery equality. Are you sure she's a mix? And I'll try to check her for mites today, but I haven't really seen her over-grooming (but... She does seem to take more dust bathes than the other hens). I do have a rrooster,but he tends to stay away from her. Idk if she's stressed, she seems pretty happy. Fairly high up on the pecking order...
She certainly doesn't look to be pure bred. I have seen ' incomplete ' lacing on some SLW but she also looks to be a little on the ' small side ' for the breed.
There are several causes for feather damage, over sexing by your roo, what is the ratio of hens to roo in your pen ? Lice / mites , poor nutrition, birds that are methionine deficient tend to have poor feather development and reduced growth . In an attempt to satisfy their craving for amino acids , they will often eat their own feathers and sometimes that of their flock mates.
