You have some interesting birds
@Peskypigeon !
My hens do not coo. They grunt a lot when reached for, more than males. They do not claim nesting boxes till their male does. Mine never will call their male to the nest, only the males call the hens. But, I only raise racers and Portuguese tumblers, so I know what to look for at this point. I can accurately predict gender before 4 months of age in my birds, when i can hold them. Hens fly better on loft flys, not always tosses though. But for someone else's birds, I guess I am not good at guessing yet... Haha.
@degunuts Have you felt between the pelvic bones? Hens may or may not be wider apart, for egg laying. They may for may not, since she or he hasn't laid yet. But, once a little older, hens will be wider apart, and males will have a smaller gap.
