My all white Americauna came out of the coop with blood on her this morning. I crated her because they were picking at her and i had to leave. It's not her blood as far as i can tell-couldn't find any injuries (also can't find who it did come from). How can i get the marks off her? I was thinking of trying peroxide on cotton balls? It's way too cold to bathe her, which i don't think she'd tollerate anyhow.
