Originally, I was looking for a 'He' or 'She' answer. Again, way more info than I was initially looking for, but fascinating info. Crazy little rabbit-hole this opened up. Thanks!
Wow. That's a lot of info(admittedly, mostly over my head), thanks for that. So the consensus seems that this is a hen, which is a bonus. I'll keep her and see what we've got.
I have a new flock of sex-links(12 roosters, 13 hens), and most of the roosters are almost ready to "graduate". I have one rooster(white coloured) who, other than the fact that he is white(which SHOULD make him/her male), LOOKS more like a hen(who are all red). No comb, small tail, etc.
Is it...
