I just checked some pictures out and it looks like the hens do a have little bit of green on their tails. Ok! Not worried anymore! Thanks everyone!My SLW (hatchery bird) also had me worried for a while as a chick until they were 4 or 5 months old. She didn't act differently than the others, but her comb was decidedly more pink (it was also a single comb). The green sheen doesn't mean boy, hens with black feathers can have an impressive amount of "beetle green" as it's called too. If you post pictures, people here can take an educated guess as to whether or not you have a boy.
