I'm guessing and it's just a wild guess that the white ones are probably for the most part White Leghorns Roos used as packing peanuts. Since it's really cold right now hatcheries pack a lot of packing peanuts.
Not 100% sure but seems like you might have some Silver Laced Wyandottes, some Welsummers, some Golden Laced Wyandottes, the white ones might be Leghorns.
