My internet search turned up nothing. If anyone knows how it works, I'm very interested. I would find it really interesting if a cross only made one or the other. My guess was that it would be like a dog, cross a big one w/a small one and you get a medium one
my guess would be medium too, like a dog or a horse or a person (that's what usually happens anyway with those animals).... but I know nothing about breeding chickens.
