I have a new hen added to the flock. I thought they had all integrated well. I was wrong. Here are some pics of what I believe my rooster did to her. I separated her, yesterday after finding this. Today I poured saline solution over this wound, then I applied betadine. She doesn’t take water or food. The comb is swollen and she’s lethargic. Could this black on the one side be a scab. Any other would be appreciated
