Wow, that is a very interesting read! And definitive as you can get - it's the exact recipe on how they are made! I think this is going to be my side project... I've been thinking about getting rid of the White Rocks, 3 true breeds is a bit too much to keep track of. But having Delawares makes...
Here's my thought on that: I have White Rocks, Dels, and White Cornish. So if I mix a White Cornish over White Rock, then that best roo over Del, I should get something similar, correct? I know that oversimplifies it a bit, but would that be heading in the right direction?
To be honest, I don't...
I'm also eager to hear some answers on these questions. I have experience with a few heritage breeds from hatcheries, and I can say that you should stay away from hatcheries if that is your plan. They do create great fast-growing hybrids though, and my only experience there is with Cornish...
