Light Brahma or pea comb gender help

[chicksnbullies]

Help! My 14 light brahmas are now 3 months old and I STILL can't tell which are pullets vs cockerals! I had someone tell me they believe all but 1 are cockerals. That was dissapointing. I really want to know soon so I can start rehoming the boys. These are my first chickens, so I welcome all advice.

It might help if you could get separate larger pics of them as it's hard to see because they're small. My guess would be that most of them are cockerels. I'm leaning toward pullet for POSSIBLY #1,5,11 (if you're counting up and down not across.) My buff brahma are 11 weeks and none of them have combs or wattles that big and red yet.
Here's a pic of 2 of my 11 week old buff brahma.
