What do we have here?

[Know it All]

I think that's a Wyandotte as well. You have the idea! We can be sure it's a Wyandotte because of it's body type (heavy), rose comb, unfeathered legs, and coloring. The Tractor Supply was saying that they had bantams (small chickens) that were straight run (unsexed), and by 'mixed breed' they meant that there were all sorts of breed in the tank. Hope that clarifies things!
