Nope, not my jam. I still haven't seen anyone post solid side-by-side taste tests with other dual purpose breeds or Cornish X, nor have I seen any carcass pictures or weights verified. I'm sticking with my Barred Rocks and may do some Cornish X here and there. The Bresse don't interest me nearly enough to build more pens and coops in order to keep them.
I only had to eat one Bresse to cycle out everything that wasn't a Bresse or Marans or a project out of my flocks. Then I gave a serious upgrade to the hatch room with a cabinet incubator and then we built a new coop with daily pasture access to grow them out in.
Our first year out here we invited 16 cockerels to dinner. I could not eat another EE ever again. LOL
After the Bresse we did a store bought Cornish again just to make sure this was all worth it. That poor brine soaked so-called chicken didn't even stand a chance. I mean it was good, chicken will always taste like chicken. The variations from one chicken to another is little differences in texture, how big the breast is (or isn't), what color and texture the thigh is, what the skin is like (the Bresse has very delicate skin, compared to a Marans that have a noticeable difference in skin thickness.) The shape of the skeleton and how the meat lays across it. How it was finished, how long it sat before cooking, the cooking method versus the type of bird...
We're going into this next season with scales too.
This is a 28 week BC Marans when his attitude went South and his comb sprouted side sprigs. The Bresse we did had a lot more breast meat but less thigh, the Bresse had been 20 weeks. Didn't have the scales then to know a weight difference.
Was toying with the idea of growing some Cornish out in one of the pasture tractors for a better side by side, being of the same feed/lifestyle. I know they'll get bigger faster... nothing will grow like a CornishX does. We have a deep freezer now too so having to do them all at once isn't a deal breaker anymore. We originally went dual purpose to avoid the all-at-once harvest of CornishX, as well as to provide an out for the extra cockerels resulting from breeding.
I have 1 extra Bresse cockerel growing out with some Marans and Oilve Eggers. We'll see how he finishes out, cull that he is. His brother is much larger and shot up fast, he stays for further evaluation later.
