I'm wondering if these really are pullets. They sometimes jump on other chickens and can be quite aggressive towards my sebright rooster. There is also a silkie butt in the photo. I can provide more photos if necessary.
I'd say that your Silver-Laced and Golden-Laced are males. The crest feathers look pretty pointy, and females would have blunt ones. Your White-Crested Black looks like a female, though. Very pretty birds!
Polish girls tend to have a "ball" crest as compared to a "flattened" crest on the males when viewed from the side. The feathers being pointy can mean roo too. What age are they?
