Help me figure it out!

Hi everyone,

We are first timer chicken owners and we’ve bought several chicks from a couple different local breeders. They were all supposed to be pullets but I am wondering if our pretty gray Easter Egger is actually a roo. He/she has been squaring up with our other bigger checks and has pretty significant comb development. The Faverolle mix im certain is a roo but I’ve included his handsome self too.

How old are they all? I'd definitely say the first and last ones are cockerels
