Yeah, I was wondering this, also. I dunno, though; if Cornish are genetically bred to grow huge muscles...if you displaced those genetics onto a larger framed bird, would they then produce a bird that is larger, with even larger muscles?
What I'm thinking is this:
1-If i hatch my own meat birds the cost will be small
2-The Cornish x cockerels are nasty pieces of work so I need another breed. I'm hatching JG right now!!
3-JG x Cornishx= big bird, slower growing with more bone to hold weight and still well muscled
What do you guys think. Does that make sense or am I missing something??
Sorry, lurker here.
From what I've read, neither the males or the females x's will live long enough to reproduce. They were engineered to be killed before 12 weeks old, therefore, even with the females and a JG roo, they would not live long enough to produce an egg, let alone a fertile one.
Have you thought about learning to caponize your males? It's a controversial subject, but from what I've read, it can produce a substantial meat gain. I don't know if the thread still exists or not, because some overly sentimental people created a ruckus on it, but it was fascinating, even if you don't plan on doing it yourself.
And, I need to ask, just how much meat does one need on a bird? The JG's I've met are pushing 14 lbs live weight.
