"Hawaii’s feral chickens are, today, a genetic blend of Jungle Fowl, fighting birds, and a host of domestic breeds. Mostly they look like Jungle Fowl. They are small, quick, and adaptable. And quite noisy."

But my question is how do they taste?

A little like spotted owl.

Not good, fresh from the jungle. The locals make them more palatable by catching them and feeding them chicken food for a couple of weeks. I imagine cooking them with a LOT of spices, as jerk chicken or chicken adobo, is probably the preferred method.

If you are used to American A&P chicken, it has much less flavor than do “heritage chickens”.

People living today who used to eat heritage chicken find A&P chicken distasteful by comparison.

So, before trying to eat Hawaiian feral chicken, I would suggest having a go with heritage chicken first. You might find it delectable, or you might find it gamey.
