Ok. I just hatched out 10 and after reading a post on them I am worried they might not be pure white. So, I have seen topics on them and what to look for. After looking at mine I see some have a black/brown spot on the head and some do not. I would like to get my AM's to be whtie meat if they are not already and I know that may be hard to do. So I am hoping they are white meat now!!!!! Anyways, what is up withthe spot on the head.
