Pullet or cockerel

[chicken-mama12]

Hello everyone,
I am a new chicken mama and I need help determining if my chickens are pullets or cockerels. They are around 12 weeks old now. The red one is mixed with Rhode island red and Brahma. And the other one is an Easter egger. I hope these pictures help.
Thank you

Both cockerels; they have too much pronounced comb and wattle growth to be pullets

I think those are both cockerels.

Sorry, but those are both cockerels.

Thank you! I was hoping they were pullets. My heart is broken I have two more if y'all don't mind looking at their pictures and determining whether they are a pullet or a cockerel . 12 weeks old as well. I appreciate your help
