Im going to say at the best of my ability without knowing how old they are, the one on the far right is almost definately a roo. The one in the middle looks like it could go either way, although it has a big comb I have a couple of BO girls that have pretty big coms, and they came in early. I swore they were boys till they started layin eggs.
The far left one is definately a pullet, smaller, hardly any comb, smaller legs, yep pullet. Oh another thing on the far right one that makes me tink it is a boy is that the neck feathers are coming in a darker buff color and he is getting some long saddle feathers in.
