Chicken novice here with 10 wk olds

Thanks to everyone for the responses. At this point I'd just be happy if at least 2 are hens.

Can I just ask what characteristics you're looking at that would make you think Cheeks is a roo but the twins both hens? When I look at them I think, based on Cheeks' comb and wattles compared to the twins, that Cheeks looks more like a hen than the twins.
