I would love to know what these beauties are. I think the red are either RIR or production reds? The goose stepping chick in the seventh pic is the smallest of the bunch, almost bantam sized. Her name is Minnow. The only silver headed (two pics of her) is named Ermine. The white is Comet.
The one leaning down in the third or fourth picture (brown with buff color around his/her neck) looks like my Brown Leghorns--which also look similar to my Welsummers. I find it hard to tell them apart, even though supposedly they have different colored ears (which I have yet to figure out.)
That's about all the help I can give you!! (first flock of chicks and they're 6-weeks old, so I'm no expert!)
