Illia one of my lav roos was taken by a fox a while back and managed to escape. If your hen has cuts and scratches and heavy damage where feathers were ripped out, I found that "Wonder Dust" a powder made for horses was great. I bought mine at the feed store. It was a great color for my lav birds. Squirt it on, dries up the wound and the other birds won't peck because the blood is dried and and disguised by the powder. It really was a wonder and I will use it again the next time I have an injured bird. He made a full, uncomplicated recovery.
