Plausibility check: domesticated rails?

I was wondering if domesticated rails ( https://en.wikipedia.org/wiki/Rail_(bird)) were plausible as a chicken equivalent? Where in the world could this occur?

If there's a species docile enough to be eventually domesticated, and one that produces enough meat or eggs to be of use, I don't see why it couldn't happen somewhere in the world. That said, it'd need to be somewhere where ducks, chickens, or geese, aren't commonplace or easily accessible from the onset, since domestication takes several generations.

I've always thought pheasants were the more likely substitute to chickens, personally.
 
In New Zealand, there's a type of rail called a weka. They are said to be relatively easy to catch as they are bold and curious, but they are also mischievous in nature and sometimes raid vegetable gardens and steal poultry, dog and cat food. They're also drawn to homes and campsites where they'll take food scraps, or anything unfamiliar and transportable really. With that being said, the Maori apparently used weka as a source of food, perfume, feathers in clothing, and lures to catch dogs. They're also aggressive (especially in the case of males) and not as predator-naive as many other island birds, and can kill stoats and rats, but they're defenceless against cats and dogs.

OTL, the Maori weren't in New Zealand long enough before Europeans arrived to domesticate the weka, and the Europeans brought chickens, ducks, and geese along with them, so there's no real need for it. They're also still vulnerable to rats and stoats despite being able to put up a fight. In the case of New Zealand's ground-dwelling endemic birds, it isn't so much the death of the bird itself that makes them vulnerable, but the destruction of their nests and eggs, which makes population replacement at a sustainable rate incredibly difficult.

Domestication could potentially solve the latter problem, since eggs and chicks will be protected by human interference, but again, the biggest drive for domestication is utilisation, and domesticating the weka serves no purpose not already fulfilled by the domesticates Europeans brought along when they arrived. Additionally, the fact that they were so easy to catch removes any need to breed them artificially; they were easy to hunt, therefore there's no force driving the Maori to keep them in large numbers (besides which, they also aren't a social species, unlike chickens, ducks, etc., which form flocks. Most New Zealand birds live pretty solitary lives).
