Our Lavender Orpingtons will be 11 wks old on Wednesday. We've been trying to band the ones that we are certain are roosters, but a few of them seem to fall somewhere in between what is obviously a rooster or what is obviously a hen. Can anyone help? Here is a collage of some of our chickens. We have 22, and about 8 of them look like the ones marked rooster here, 11 are clearly hens, but about 3 of them look like the bird on the right - its comb is about half as high as the roos, still kind of yellow-ish, and just the beginnings of wattles (unlike the roos, which are now quite pronounced). They are all the same age, almost 11 wks. Thoughts? Thanks!
