Cool! I think you will be pleased with at least the Whites (if they are the same stock I got).
I really have mixed feelings about MPC. I would probably not order from them again unless it was a good deal and I *did* end up with roos in my order (at least three so far, the Silkies are too young to tell).
So anyway, I got Black, Buff, and White Silkies (as well as a couple other breeds). The Blacks are typical hatchery quality. The Buffs are perhaps slightly above hatchery quality. The Whites are WAY above normal hatchery quality birds. All three of them are gorgeous birds. I hope yours turn out the same!
