Barnevelder babies. Pullets?

[Featherlyadvice]

I have a 7 week old, 5 week old, and two 3 week olds. The younger ones just had their combs turn much redder than the older ones and it made me question their sex. Would anyone like to hazard a guess?
My two young ones with red combs starting.

My oldest one is 7 weeks

And the 5 week old

I'd guess those two younger birds are cockerels based on their pink combs. The other two appear to be pullets though, but they are pretty young still...

Thanks guys! I wasn't wanting any roos, but after seeing a few pics of them on the barnevelder breeder board, those are some handsome birds!
