Serama-mix gender ?

About 6 weeks old. Was told the chick on the left came from a sebright mom and serama dad.
Boy or girl?
The blue chick I think was an old English. We’re assuming rooster with a comb like that…?

Could anyone give me tips on sexing seramas also? What about mixed breeds like these?

Sadly both are boy's. with chicks at that age, your looking for red comb and wattles. With both mixed breeds and seramas.
