What breed are my chickens? And are they male or female?

I know that I'm not the OP, but could you tell me why you think so? I"m trying to improve on sexing birds.

Combs. At six weeks these combs are pretty red and developed. I agree that #2 is the only pullet.

Your first bird there reminds me of this one I just saw, and looking it up this 'breed' is available from My Pet Chicken.

Hi thank you everyone for your help! If I have mostly cockerels then I would have rehome some of them which is a shame since I’ve grown so attached to them. I guess I’ll just have to wait and see which ones will start crowing in a few months.
