I agree that factory farming is awful, but cornish X are not a genetic mistake, they are a genetic marvel! Home raised CX are not sad if you give them a good, albeit short, life. You'd have to raise and kill 3 times as many dual purpose birds to match the CX.
For sure, very true, the males are definitely aggressive once they reach a certain age and wrangling to butcher, yep, better have at least two people at butchering time, they get really big and strong.
You're so right about the cost too, especially now with the feed prices being so high...
Just curious, how so? I've had BBW a few times and I just raised them exactly like broilers other than using game bird feed and it taking a little longer to grow them out.
