We bought them from a man who hatches chicks, yes. But it's more of a business than a hobby- he claims to have over 500 birds. Initially we got 12, and were told there were RIR's. And out of the 11 that survived, all but one were dark colored, truly RIR looking. At age 6 weeks, we took 5 roosters and traded them for hens that were supposedly the same age, and also RIR. None of them were reddish.
In the tomato picture on my post, the one with the tomato, and the one next to it, the darker ones, are from the original group.
We never saw "the farm" where the chickens lived. So we really don't know what was running around there. All we know is he sold RIR's and Buff O's No other breed mentioned.
As of now, they are just 16 weeks old, so it'll be another month before they start laying.
They are sweet birds, no matter what the mix. And kinda pretty in their own way ( except that poor mutt roo LOL)
