As I stated before our black chickens Silver And Shadow have suddenly become aggressive. Most importantly have been aggressive towards our golden brown buff Artemis. I had said sure Artemis did cause some damage a tear of sorts to Shadow or Silver's ear area. But for the most part they have been the aggressors so far. Last I had seen Artemis was in the cage with fellow buff Serena this morning all fine. I thought before ok she is still scared to come down its fine. Just a while ago I thought to check up on them. I saw Serena pretty much hanging around this time with the bad girls. I thought ok lets see how Artemis is doing. I come back to check and I see her in the corner with one leg up. I thought oh she must be doing a flamingo thing my parakeets used to do the same. I did notice red spotting in places and like a few drag marks. Then I realized something must have happened. I finally was able to see why she was holding her foot up. It seems they injured her. I assume it was those two aggressive bad girls. I can see where the blood is dry perhaps but her nail isnt long anymore. I was wondering what kind of care can I give her and what can I do so she can heal and will it grow back like human nails do?
