true, vaulted skulls doesn't affect every bird. but (at least around here) about 75% have been crossed with polish, and silkies are a weaker breed anyways so separating them from other birds will always help with livability.
I can only speak for my own flock, but vaulted skulls affects about 45-50%. that's a quick way to lose about half of them if you mix them with aggressive young chicks.
