Here are some pictures at 2 weeks to show the various color patterns. I think they're some dual purpose ranger type. Also pretty sure there are a ton of roos here. Oh well.
I like to play the "what kind of chicken is this?" game too. Last year I bought a straight run Heavy Breed Assortment from Murray McMurray. As soon as I got them, I was looking a their online catalog for pictures of chick in their breed descriptions, and as they started feathering out, looking some more!
Here's an update with my favorite roo from the group. He's gorgeous. Going to try to find a home for him because i've never seen a rooster with this pattern, otherwise into the freezer.
