So I've read on here, injection site abscesses are common..so here is my question. I got a bottle baby exactly a month ago..the day I brought him home he was 4 days old and he got his cd/t then. He has had a large soft lump where he got his shot that is about the size of a quarter. There is no hair on it and it feels warm to the touch. I have left it alone as you guys said these are common, but the lumps on the other goats have gone away and this one is still the same size, and now has no hair on it. How do I treat it?
