Mixed breed gender help

[NTroyer]

Hello! I hatched 11 eggs this summer. (What a fun experience!)They are about 12 weeks old. The roo is a golden lace wyandott. The hens of the chicks in question are Brahma and Easter egger, I think. I'm thinking the brahmas might be roosters. I thought I read that for this mix, if the babies look like the hen, then they're boys? But I could definitely have that wrong. I would love any opinions. Thanks!

The white and black patterned birds are cockerels and the EE is a pullet.
