If you're looking for a big breasted, early grower that can naturally reproduce check out
@duluthralphie 's Toads. I plan on getting some this spring. For simplicity, I also do CXs, 3 weeks in the brooder, 35 days on grass and off to the freezer.
ETA: If you think back to the 60's, you couldn't buy a cutup chicken and if you wanted to grill it or fry it, you went for a 3lbs bird. 4-6lbs would be rotisserie or roasted. You, could of course pay the butcher to cut it up for you.
