I decided to make my own jumbo cornish crosses, sooooooooooo I ordered 5 standard white-laced red cornish pullets and a white rock rooster. I'm so excited!! Wish me luck, they will be here in April.
Good luck, just so you aren't disapointed, they won't be as big or fast growing as cornish x's, because the parent strains for those meat birds have 40 years of selective breeding for each parent strains so the offspring are even bigger.
Well... Some people are working on meat birds so you might want to see if you can't find their posts... something tells me they won't grow nearly as fast as the cornish x and they will be meatier than your dual purpose birds... but still take as much time to get big enough...
Ok, I got the standard cornish hens (8lbs plucked and in the freezer) and a white rock rooster (10 1/2lbs plucked and in the freezer, lol). Well, it can't hurt to try. Maybe just a couple more weeks after 8 weeks old and they'll be big. I'll let ya'll know how they turn out but first I have to let the parents grow up before they can make their own babies, lol.
