Question on silkie chicks

[Julie's Silkies]

I have some chicks that have like a round buff ball on the top of the head and some that dont, anyone know.

The ones with the round puff probably have a vaulted skull. Feel their heads and see if the puffy ones feel just a tad soft in the head, just don't squeeze!

Yes, some have the vaulted skulls and some don't. Does that answer your question?
