ok i have some eggs from a friend that i am going to try and hatch the roosters are two doms and then theres 2 barred rocks and a dom hen in the pen as they are for sell (there is no fighting or anything no feather plucking from matting nothing whats so ever hens have to be with roosters or the roosters will fight). i was woundering if they could be sexed by the headspot or the slate wash down the front of the chicks legs?
