As for gender, it's just too early. I was convinced my roo was a roo but then around 7 weeks, I just wasn't seeing the typical roo indicators. He looked and acted like a pullet. Weeks went by and I finally stopped worrying and let myself get exited that I had 3 pullets. Nope. I'd have to go back and check but I think it was around 10 weeks that I finally saw the hackle and saddle feathers I'd been looking for.
