Hope I posted this in the proper place..

Jumbo Cornish X Rocks
You see a note like this:

"Please Note: Jumbo Cornish X Rocks are hybrids. Therefore we do not recommend breeding,
they will not produce the same high quality in the next generation and due to the extreme
rate of growth they will be too large at time of sexual maturity to breed successfully."

Yet I'd like to raise my own to butcher if I could. I'M sure one can.
Maybe even buy eggs I know as they get older they have leg problems.
Mostly just a question..

Thanks y'all

What's your question?

Welcome! If you are asking about raising Cornishx chicks to maturity and breeding them, it's not going to go well. They are designed to be butchered at about eight weeks of age, and few if any will survive to maturity, much less be able to breed! Their hearts and joints fail, and it's sad and ugly. Then, they are hybrids of two or more proprietary breeding lines at the commercial hatcheries, and won't reproduce themselves anyway. Consider the white Cornish instead! Mary

Okay what combos of breads do they use to make a Jumbo Cornish X Rocks..
I heard a plymouth rock might be the hen.
Does any one know what the combination is?

I apologize for not explaining better what I was looking for I hope this suffice!

I believe originally it was a Cornish crossed with a white rock, but generations of selective breeding has produced the birds seen now, so I don't think you can just cross those breeds and get the same birds with the same growth rate. Potentially if you can keep some alive and on the thin side they could potentially reproduce at a decreased rate, though offspring may or may not be the same. That's my understanding of them.
