One of my Columbia Rocks keeps getting picked on by the other chickens (Columbia Rocks and Red Rock Cross). I usually try to catch it in time and treat the wounds, but this time it seems like they attacked her. Her whole lower back near her vent has been gouged. It's like they're eating her! I've been putting Blood Stop Powder on the fresh wounds, and that has helped her form a scab over it. Since she is white-feathered, and her scab is dark, it attracts the other chickens to come peck at it again. I have also been putting corn starch powder on the scab, to make it less noticeable, but it doesn't stay for very long. I have tried Stop Pick, the red paste stuff, but it doesn't seem to be working, at all! If anything, it marinates the poor chicken and attracts all the other chickens to come pick at her even more. The Stop Pick smells like barbecue sauce, to me anyway. This same chicken has had this problem before, and she was healing slowly, but she still hasn't healed totally from the previous wound. She's a strong bird, so I have no doubt that she will eventually heal up again, but until then, is there something I can do or use to stop any more picking? Also, I wonder if there is some way to help her heal faster, or put something on the wound to hide it until she is healed?
