I wondered on a previous thread if six of my eight black sex link chicks were roosters. Then I found something that said that, as soon as they hatched, the males had a white spot on the top of their heads. I had thought that any white on the neck area was included in that but apparently not. Can anyone clarify for me? Is it white on the top of the head or white anywhere on the head/neck area. I'm sorry, but I'm kind of new to the little ones.
