I'm having a blast watching my McMurray rainbow variety grow and change. My poor family is neglected because I can't seem to drag myself away from the chicks. So I've got two that I've diagnosed already as cockerels, cute little guys. I just wonder if my reasoning is anywhere near sound when it comes to this judgment. SO... how accurate is it that with American breeds, cockerels tend to feather out more slowly? For example... this 12 day old GLW chick next to a RIR. Sorry, no other wyandotte to compare him/her/it to... I'm guessing the GLW is a cockerel. Notice his wings are barely coming in and he has no sign of tail feathers yet. AND... here are two of my 5 silver-spangled hamburgs. One is much larger than the rest, and one is much smaller than the rest. This pic is of the larger one and one of the medium-size chicks. I'm thinking that because this chick is so much bigger, he's a European breed and he's feathering out quickly with a much longer tail, and he's much more flighty and outgoing than the others, that makes him a boy. What do you think?
