We have 12 hens and 1 rooster. 4 of those hens are older chickens and are full grown adults. The other 8 range from what I would consider an early teen to teenager in chicken (sorry, haven't had chickens long, so I don't know technical terms, but about 4 of those 8 are laying, the others are not) One of the older hens is small and the rooster is very rough on her! The feathers on her back look horrible! My daughter and I noticed tonight that her back is actually raw! We now have her separated from everyone else, but was wondering if it would be ok to put Neosporin on her back where it's raw looking.
