The two closest look like boys at that age and the rest I'd say were pullets (though I've had a couple of bantam pullets trick me as they were more developed and pinker in the comb from a young age, but those two front ones do look to have big, pink combs). I know cross breeds can be tricky as you never quite know what is influencing their development or how quickly they will mature. And I know it can be torture, wondering which are boys or girls!
