That would be fine with dark meat, which is fattier and has a lot of connective tissue which needs to dissolve, but white meat is generally juicier when cooked at a higher temperature.
Also, it is important heat poultry quick enough to get it past the lower, more dangerous temperatures.
Cooking low and slow normally entails cooking temps around 225-250F, way beyond the target temps: white meat:165F dark meat:175F.
The technique requires one hour at 350 degrees to kill off anything bad, then 1 hr per pound, as I remember at the final temp - maybe 170. The technique was most impressive on rare roast beef. The outside was black and the inside was a perfect, completely uniform 130 or 140. No gradation of more done meat near the outside. Just a perfect roast.
