LOL. I know it is too early to tell. I'm just hoping a get at least one girl of each breed to add to my yard art chicken flock. they are sure cute though. One of the BR's is absolutely out of control already. He/she doesn't listen to mom until she gets firm with him/her and runs off to do his/her own thing all the time. I feel for Graycie. That chick is a challenge.Sharol I haven't a clue. Often the girls get longer tails first, but both breeds develop quite impressive combs early regardless of sex so I can't tell by that. So in the three sussex for instance if two have longer tails I would guess those to be girls. The BR don't develop tails as quickly and I can only tell those as they feather in because they boys feather in a lot finer. My newest hatches however all have fine feathering so I just don't know either. I was trying to raise a few for future breeders. I need a back up rooster and more girls. I guess time will tell.
