They hatched on 6/16, 6/17, and 6/18 and are doing well. I want them to be friendly so I'm trying to hold them often. With this picture can anyone tell me if they can be sexed by the wing feathers? I heard that only certain breeds can be wing feather sexed. If they are one of those eligible breeds does anyone think they can tell if I post pictures of their wing feathers. I'm hoping for hens so I can keep them. How long until they will be full grown? So far the first hen is going to be named Consuela.
