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.
