Here are my 15 at about 2 weeks of age. I bought the white/brown/rare assortments from Meyer (along with a splash maran, copper maran, and a blue ameracauna males but I also had 3 deaths in the first couple days and wasn't sure of what breeds passed) and have some ideas as to what some of the breeds are.
? This one has darker legs than the other ones pictured above or below.

The 3 in the top pic look like RIRs to me.
The one on the left in the middle pic looks like a Welsummer
The bottom pic looks like maybe a Silver Laced something, no head poof or furry legs so I'd guess Wyandotte though I've never personally had a laced chick but that looks like what the coloring on the feathers is coming in as.
