I haven't, but I'm going to give it a shot. I have a Buff Cornish rooster and some White Leghorn hens, and when I can set up some grow out pens, the plan is to raise them out, keep records and do the math. Someone mentioned that their 3 heavy hens would pump out 14 eggs a week - 3 WL will do 21 in a week, as will Sex Links, and BRs or Buff Orps will do about 18, which makes cross-breeding the way to go, unless you really just want a project. Also, all of those are bred for early maturity, and if you want to raise meat birds, you really, REALLY want to breed HARD for early maturity. Otherwise you have birds that grow frame rather than meat (or eggs)Have you tried this cross the other way, with Leghorn hens and a dual purpose rooster? I wonder if it would produce similar results with the added bonus of a lot more eggs from the breeder flock.
I'm not thinking that the Buff Cornish/WL cross will be amazing, but I enjoy genetics and math, and then I'll have that data for when people ask, because honestly I can't think of a better way to get decent breast meat on a non-CX.
Just a bit of advice, from someone who's been doing this a while, and sold to the public. You *might* be able to sell "heritage type" chickens at your farm stand, if you market heavily and have access to clientele making at least 60k a year. Grocery stores and ESPECIALLY restaurants need absolutely consistent product. The first time you send a chef a bird with extra dark thighs or a thin breast and they go "I can't sell this" is the last time you sell anything to that restaurant, or any restaurant in town as soon as the word gets out, and it will. You will have to be able to send them 20, 4# birds a week, who, if parted out will give X weight of breast and X weight of thigh and drums, which should cook up to X shade consistently (Or whatever number and weight they order). Because if there are 2 people at the table who ordered the chicken and they're going "Mine is really dark, is yours dark?", "That one is bigger" you're out of business.I'm not just looking for good meat breeds, I'm starting my own chicken hatchery. But in the process I'm also hoping down the road to become my own certified processor allowing me to sell directly to the public and local grocery stores/restaurants.
Also, please know that Joel Salatin's hobby is raising birds, his multi-million dollar business is selling books and appearances.
Well, my meat birds are always healthy until I butcher them, happy as clams for 8 weeks and are very productive of meat. If you want a meat bird that produces eggs, and that's what's important to you - go for it! I wish you success, please keep records and share them! I just want to point out;But as of today, I'm after a chicken breed that is sustainable, healthy and can live a productive happy life, after all, I am what I eat.
I've been a member of this forum for 12 years, and the forum is older than that. Plenty of time to develop a breed. There are over 15,000 threads in Meat Birds, and at least half of them are about "I don't want to raise CX because I hate/don't understand a terminal cross." Not One of those people have come back here going "Success!!!"
The best you'll hear is "Well, I have X and they do ok, I raise them for 5-6 months and they're way more expensive, but we don't eat a lot of chicken and I'm happy with it, which is what matters."
Now, yes, if they're happy, that's what matters! But for your goals, nobody - and really, nobody - is selling any significant amount of meat from birds they keep a breeder flock of. You have people selling Freedom Rangers - which you're also buying chicks to do - and people who sell a couple of their specialty birds here and there, but absolutely no one who is paying the feed bill with meat sales of birds they bred and raised. 0%.
But, hey, maybe it can be done! Maybe you'll read through and see a gap the rest of us haven't. It happens! I don't think it's likely, but it's certainly possible. Just make sure you check out what at least 7,000 people right here have been up to for well over a decade - that's a lot of education, y'know?
