Aside, from the obvious answer, of being when they are old enough to do that, which roosters and hens do, best, when should I be able to take info gleaned from you folks, and reliably determine gender, on some of my babies? I have 12 of 20 chicks ordered, who have survived a predator getting access to the grow out pen, that were ordered straight run. Another ten, were ordered as females, and then, there's the "mystery chick", most certainly a male. They hatched around June 22, it's getting close to caponizing time. How do I determine which is what gender?
