Light Brahma hen or roo?

[Buckbuckbuckbarkkkkk]

This light Brahma was sold to me as a pullet. I’m now getting a bit worried it may infact be a rooster!!
Can anyone confirm? It’s about 12 weeks old

This one may need more time. Right now nothing screams cockerel to me, but I can't rule out slow developing male either.

I've seen plenty of pullets with combs that pink at 12 weeks, but brahma are usually slow to mature. The comb is incorrect type (brahma have pea combs) but not overly large for a single comb. And I don't see any male specific saddle feathers coming in. Although at 12 weeks a slow developing cockerel might not have male specific feathers yet.
