We are raising 9 chicks who are currently about six weeks old. Today we came home and heard a cry come from one. We found that my salmon fav had had most of her back feathers pulled out. Some spots were bleeding and most of the area up to her neck was bare. This raised a bunch of questions. 1. We put no peck gel on her but not directly on the wounded area. I know it has cayenne pepper in it to deter the birds, so I was hesitant about putting it directly on raw skin. Would it irritate the injury at all? 2. Their food was empty all day. Could this be the probable cause of this? 3. What's the best way to care for the wound? Do I put neosporin or isolate her until it heals or just leave it alone? 4. We spent most of the night observing the birds. We have a gold sex link that I saw 5+ times go peck the salmon, despite having full food. She also pecked 3 other birds, enough to elicit a screech. Is it possible that such damage could have been done from one bird alone? What do you do if one bird is dangerously aggressive? I have photos that I will post as well. Any advice would be ,much appreciated!
