Fowl Stuff Ameraucana Lavender and Black

[maggiemo]

These birds are about 11 weeks old. The bantams are pretty obvious but the two large birds, one lavender on the far right, and one black, are really hard for me to tell if they are cockrels or pullets.
These are also the hardest birds I have ever tried to photograph!
The far right lavender bird and the black bird are the ones I am questioning. Pullet or roo?






Piture of the bantams, just incase someone wants to see John Blehms birds, very sweet and pretty IMO. All are 10 or 11 weeks old.






Thanks for looking.

The combs look small so I'm guessing they're both pullets. But it's difficult to tell on solid colored birds with pea combs. Check to see of there are any of the narrow, pointed sex feathers in their necks or saddles, or if there are sickle feathers.

Thanks for looking! I read about the pointed feathers, but I am not sure I would know what I am looking at. I will try to catch them and see if I see anything that looks pointy.
Do you know if bantams mature faster than large fowl? The bantams are obvious who are roos and who are pullets.
Thanks!
Anyone else want to chime in with an opinion?
