Question About Polish

[BeckyLa]

I just love my new Polish! So I hatched some of their eggs and got the cutest ever babies. When they were born I noticed they have a vaulted skull. Is this a Polish trait? I knew Silkies have this but I didn't know about Polish. Or do all crested chickens have a vaulted skull?

my polish all have it too. My guess is that its a crested breed thing. I also have crested ducks and tufted roman geese and they also have vaulted skulls.
