Exactly, with the addition that land race birds are not bred, they evolve, or not, without human interference.Have any mixed SFH's gone broody at all? Or is it only the pure ones that seem to not want to sit?
If the answer to the first question is no, then I might have to rethink this thing. Can't really have a landrace that won't sustain itself, can I?
To state one wants to breed a landrace chicken by deliberate breeding is like hoping to live 200 years.
Most land race breeds find a paarticular niche in their environment to exploit. To me the most extraordinary examples are the cold climate landrace breeds in places like Afghanistan and China. A Finnish friend of mine is trying to save such a breed.
There have I suspect been many cases of what I'll call feral chickens trying to establish themselves. Not many make it.
