My newly arrived Golden Buff chick has a swollen area near her vent. There is crusted blood and it's bothering her, although the other two "girls" she came with don't seem to be too interested in pecking it. I cleaned the area and put some neosporin on it. I tried separating her so there wouldn't be any pecking, but she put up such a fuss, I put her back with the others. These are my first chicks and I'm a little nervous about this. Should I be worried?
