These seven chicks are almost 3weeks old, their daddy is a GCM momma is either GCM, BCM, or EE. Any guesses as to whether they are pulleys or cockerels?
Its still young to tell; I'd wait until they're at least 8 weeks old, and then post updated photos. But all except the last one don't appear to have any obvious cockerel characteristics.
Really too early to tell. From what I can see from head spots, I'd hazard to guess #s 2,3,4,5 &7 could be roosters. but it's pretty much just speculation at this point.
