Help do I have a rooster Orpington?

[NadineIvette]

Hello I have 3 Orpington 3 1/2 week old chicks, 2 of them are larger in size. And have combs forming one of them looks like it’s turning red. Is it too soon to sex or do these look like roosters? Also the two I believe are roosters beaks have been changing color and I don’t know why.
