Likely the birds you purchase to roast are soaked in hot water prior to plucking (scalded). If your religion allows this then just hire someone to pluck your birds for you. I assume the issue is only when you do it so that solves things neatly. If you can't eat a scaled bird period I'm sad to say you likely are without knowledge of it.I've done that, and it fine when just want parts, but I often enjoy roasting a chicken whole, and the skin really keeps the bird moist.
