Hi, Everyone. I have been reading a lot of the post on here. I have been trying to find out into on if Permectin II is ok to use on my one week old chicks???? They have mits. I have 10 chicks in all at this time. 3 that are a week. 4 that are about 3 weeks old. 3 that are about 4 weeks old. I have seen the mits on the older ones and I have read if one has them they all do. Just dont want to make my 3 little ones sick. Please Help.
