What you want are true heritage line BRs, not hatchery stock. I have two lines. My Marvin Stukel line hens are very large and perfectly barred, but they are very difficult to locate. I also have a second line, the Jill Burk line. They are smaller than the Stukels, but barring is nice.There is also the Good Shepherd line to consider. You'll have the size you're looking for, I think.
These are the Stukel hens, though I have only two left now (they are aging), plus a few of their daughters. Is this what you mean? They are hefty hens.
