If I understand it right you are referring to the chickens that are not
housed in a poultry house. The native chickens are the ones that are
just roaming around in your yard and neighborhood and you just call out
to feed.

It is my understanding that these chickens developed their immunity
because they are naturally inoculated to the diseases because they are
subjected to it since hatching. These chickens feds on anything that it
finds on the ground including poop for that matter or anything that it
finds edible and does not kill them.

When I was young, which was a million and one years ago I have an uncle
in another island where he has an egg poultry farm. These chickens are
protected from the "native" chickens, regularly vaccinated and fed with
special store bought fed. It is very sensitive to anything and the way
it was explained by the veterinarian, that these chickens have lower
resistance because it is being "protected". I think the best way to
explain it is when a "balikbayans" goes back, most of them will have
LBM if they drink the water or some food that might not cause the same
reactions from the "native".

Going back to your plan to mass raise the native chickens, I imagine
that will be possible if you have large track of land and just let them
loose. Just let them live through the elements and just feed them
regularly. The weight increase rate of these chickens might not be as
what you want it to be economically feasible.
