I have a nasty chick! Out of the 9 6wk olds chicks i have 2 Delaware's. One of them is super sweet and i can get her out of the coop with the other ones just fine. But, the other Delaware is really nasty. She (or maybe he) bites me really hard. It seems to be fine with the other chicks, but just nasty with me. I have tried treats, being super slow, holding her with gloves when i can catch her. I have had this batch of chicks since day 1, and have not had an issue with this one until now. I am starting to think it may be a he. The comb is much darker red and more prominent than the other. Any suggestions?
