What breed are these 5 chickens?

[Blueeyez]

I bought a dozen chicks out of the mixed bantam bin at tractor supply a few months ago, but it is quite clear that five of them are definitely not bantams. 4 are the same color pattern (red and white), one is quite different (the brown one with the gold around its neck), but all of them are already much larger than even my adult actually bantams. Any idea what breeds the four red and white ones, or the brown one could be? Thanks

Looks like you have 4 Red Shoulder Yokohamas and a Brown Leghorn.

agreed, and a couple of those yokohamas are cockerels.

You have a brown Leghorn pullet.
I'm not sure about the others. I've never owned Yokohama before. I do think you might have a cockerel or two though.

They’re red shouldered Yokohamas. That coloring is unique to this breed. They’re quite rare! Those cockerels are going to grow some long tails.

Your birds are gorgeous! I have never heard of red shouldered Yokohamas... yay for learning something new!
