The poultry farms are MANY MANY generations down a line of hybrid birds, at least fifty generations probably of work on the CornishX they offer. The backyard chicken person has no way of doing that. The hatchery thing is a thing done over a huge period in huge numbers, we cannot reproduce it.
Which is why most of us trying in our own yards are working from the colored freedom rangers - also a head start but never going to be as fast as the CornishX - that just aren't even normal any more. AKA dead before a year even if you tried to let them live...
Colored Rangers offer an interim measure to work from if you're interested in both speed and sustainability. It means about 10 generations of adding birds like delawares and culling heavily for speed and meat production but after about five years and ten generations you can theoretically produce a ten week bird.
I'm comfortable in the 10- 12 week range and the colored rangers generally fit the bill, but then you've got to cull and sort if you want sustainability.
Answer - no simple answer. You can't replicate in your yard what the poultry industry has done in 30 years.
Frankly, I don't want to. If it can't live beyond a year, (most six months) reproduce normally, forage and be healthy, not interested in eating it.
