TSC Assorted Pullet question....

We got 6 girls in march from TSC and I didn't want to ask what they were but I've gotten to the point that I can't figure it out on my own (and maybe it's still too soon) but I'm dying to know.

I think, based on the feathers, that we have two different breeds, but I'm not sure that you can tell from the pictures. I don't care what they are because they are healthy, etc, but it's fun to be able to look up and research (because I like to use the chickens... and garden as learning opportunities!)

So, without further ado, here are our girls....



ignore the blue one... my oldest marked that one.. it's "his".... and the second picture is the older picture.... any ideas?
