Came home today and one of my silkies somehow lost massive feathers. There were her feathers all over the run and when i looked at her, there was a bald spot on her upper back and tops of wings. A very very big one. I've never seen pecking in my flock before, but just let a broody bird out of solitary. Maybe she was re-establishing herself in the flock? I also have a younger bird (3 months?) and maybe she was finding her place... If it was an attack, it had to be a bad one. Anyway, she's my favorite chicken... it made me sad. Thoughts?
