I have 3 chicks that hatched on Feb 15th - Presidents Day- we were hoping for hens but I think Abraham is a Roo because he was on top of his mom, grabbing her neck, and doing the jig...ugh! (She's a naked neck so I could see he had ahold of her good) Does this confirm he is a boy? Didn't think they had this behavior at 3 weeks! Gee
