I have one Polish who just started laying eggs and has bright red wattles. She still has a questionable poof. Go figure.
But BLP cockerels look way different once they start getting those darker brown feathers, and not a buff laced pattern. If you go to feathersite, I think they have pics...
I have been totally fooled by poof. I think the buff laced Polish are the easiest , the males start to get real dark brown feathering, like in their poof, and saddle area. It's unmistakeable. I dont' see any of that in your three.
