My Easter egger cockerel at 14 weeks. If your brahma was a cockerel, it would have a comb like his by now. Pea combs are still pea combs regardless of breed.
One of my pullets 14 weeks. Comb is a pink, fleshy color, but just starting to develop. This is what yours looks like.
Looks like a lovely 17 week old, point of lay pullet. Her comb is still flat, but should start to develop more over the next few weeks. The fact that there are no male saddle feathers by this time is also a good indication of pullet.
