I cannot see the head that well to be able to tell anything from the comb and wattles. If they have a Pea comb it can be challenging to tell much about the comb anyway. I think I see some sharp hackle feathers but no sharp saddle feathers. The legs look fairly thick. Posture looks somewhat upright. I'd give this one about a 75% chance of being a boy.
With the sharp hackle feathers, curving tail feathers, fairly thick legs, and upright posture I'd give this one about a 90% chance of being a boy.
I would not do anything dramatic with them yet but I think there is a fair chance you have one or two boys.
