these are at about two-three weeks. She seems to do a little jump and kick thing like roosters do, but that behavior seems to have stopped recently. My wife is concerned because of the comb and waddle growth has been pretty fast even when compared to the other pullets.
I think cockerel also, stands up tall like a male, and legs are thick. I am not familiar with that breed though. I'm sure others better qualified than I, will give their opinions.
