We found one of our chicks this morning with what we thought were just loose feathers hanging from it's neck but when we picked it up we found that it's skin had come off half way around it's neck. We have it put up away from the other chickens, especially since some of the other chicks were pecking at it. Should we put something on it like Neosporin??? It's 3 weeks old and healthy otherwise, we don't want to have to kill it. Please help??
