Can't help but i can tell you it took us about 2 months before we finally figured out our assorted chick order. That was half the fun of raising them. LOL Good Luck and i'm sure someone else will have an opinion.
The white ones with a single comb and yellow legs looks like White Leghorn. I see one with a "flat" comb that is white, it might be a White Wyandotte. If it has "muffs" or green legs its an Easter Egger. The white chicks that are feathering out red/brown are probably Sex link. Of courses these are just suggestions. I got the Rainbow Layer mix from MPC also and I change my opinions daily, but I love the guessing game.
ETA I see one Sliver Laced Wyandotte and two Brown Leghorns (or could be Welsummer).
