Help sexing these cuckoos

[Thatothercrazychickenlady]

Wondering if it’s safe to assume these cuckoo maran crosses (or maybe barred rock crosses) are pullets? I’ve gotten so many mixed opinions so far. 9 weeks old today. Don’t mind my other birds in the background. I got so many cockerels from my last hatch still working at finding them homes.

what are they mixed with? How were they mixed? What was the Cuckoo? Mom or dad?

If they were done in a specific way, they would have been sex linked... but I think these are all pullets.

I agree, I think they are pullets.
But it would help to know which parent was cuckoo/barred.

The rooster was barred or cuckoo. I can’t remember which eggs these guys hatched from either cuckoo maran roo over a black or blue laced Wyandotte hen or barred rock roo over RIR hen.
