There is an intermediate “meat bird” that I raised. They take about 2-3 weeks longer to hit broiler size, and top out at 9-11 pounds DRESSED. They don’t have the heart and leg problems of the current White Cornish Cross Broilers.
Not sure where else you can find them, but Whelp Hatchery sells them as “Slow Cross White Broilers”.
I still have one that is 4 years old, and she can run, and can fly short distances; she lays a huge, light tan egg almost every day of the laying season. The rest of the flock are Black Jersey Giants.
I’m so used to the size of my birds that I accidentally insulted one of our neighbors by asking if I could borrow one of her “bantams”, if she had a broody one. She has regular sized Rhode Islands. LOL
I can say we’ll never do meat birds again. Ours finished up at 5-6 pounds. Even half a bird was too big for the three of us. But thanks for the info.
