I'm very impressed with your project Ipatelski. I've thought about doing the same thing to create a stabile Cornish type chicken with a goal of a 4 pound cleaned carcass at 12 weeks. I think a true breeding, medium growth Cornish would be the answer for many Homesteaders meat bird issues. I've had chickens for years but am just getting into the breeding, bui with other livestock we stabilize new composite breeds at 3/8. I'm thinking in this case it could be 3/8 Commercial Cornish and 5/8 Dark Cornish with selection for consistent medium growth rate. Of course these are just my pipe dreams of how I would do it but please keep posting. My energy has to go into my Dorking project for the immediate future, but I'm very interested in your results.
By the way, from what I've read the commercial Cornish crosses have significantly higher resistance to Mareks Disease because of Cornel's work in the mid 20th century. That could be a real asset to your strain.
One question: are you aware of the importance of selecting for earlier feathering? If not it should help you determine growth rate of individual birds within the first couple of weeks rather than waiting months for them to grow out.

I agree I'm not sure why the goal for home grown chicken has to be a humongous turkey sized bird. I'm leaning towards smaller is better (who wants to eat the same chicken all week?) and I've been wondering if crossing bantam to standard cornish might be an idea. Or bantam cornish over dorking............
