Questionable Gender of Frizzle and RIR

[peppypeepers]

Two of my 5 Pullets are showing several distinct characteristic of a cockerel I'm 80percent sure of the frizzle but very unsure of the RIR. I appreciate any help ( they are roughly 5 weeks old)
thanks

The frizzle is definitely a boy.

The RIR's comb is pretty big, and I think it's a boy, but some of the girls get bigger combs, too. Do you have any other RIRs for comparison?

Both look like cockerels to me based on comb growth

I don't she/ he is my only RIR my 7 year old picked her and named her sparkle she will be devastated if we have to change sparkle to spunkle lol

I was pretty sure with the frizzle he has some thick feet but the RIR legs and feet give nothing away.
