Hello. I just bought three new baby chickens last Thurdsay - presumably born on Tuesday (28FEB). They apparantly sex them but I've heard somewhere there is around a 1% chance they are wrong. They are a Barred Rock, an Ameraucana, and a silver Wyandotte. Is there any behavior to look out for to indicate one might be a rooster? I know every time i reach in the Wyandotte sprints right for my hand.
