Silkie Beak Color and Purity

[ebenavides5]

Hello I just hatched a batch of silkie assorted colors, 2 of them have their beak on the lighter color, sort of tan color and their feet are light colored too. These two chicks are buff by the way

This is from a reliable private seller on ebay which ive bought from before, and just wondering if there is some mixing somewhere or if this will change back to darker beak and feet with time?

thanks

I think a silkie - pure should have only black grey beak and skin. But in new with silkies
