My 22 week old hen, Jasmine, was fully integrated into my flock of 6 (same age-ish) a bit over a month ago. Everything was going well, a little chasing from my Speckled Sussex, Raya, but otherwise she was cautiously happy. My Austra White, Elsa, was previously a very timid thing but when she started laying last week, she started being aggressive toward my new hen. I noticed yesterday that Jasmine was hiding out in a nesting box all day but I didn't notice much bullying. I separated her for a bit so she could get her food and water and relax. Today I went out and found Elsa had cornered her and was just pecking at her. I cleaned her wound with VetRx, put Blu kote on, covered the area with an apron so flies don't get near it and gave her vitamin/electrolyte water. I separated her into a dog kennel. And bought pinless peepers for Elsa. I'm praying once she heals and goes back to the flock that the peepers will stop the pecking. I'm not familiar with peepers. How long should they stay on? Does it help change the behavior for good? Do I need to change them out periodically? Does it hurt them? Also, did I do everything I am supposed to for my poor Jasmine? Lastly, I what point do you start thinking about rehoming? Thank you for your help!! It all happened so fast.
