I use just your typical propane turkey fryer. Like others have said adjusting temp can be an issue. Too low outside & it can go out. I started doing all my scalding in my outside shop garage. No wind makes adjusting for lower Temps easier without flame outs.I use a turkey fryer pot on a camp stove — meat thermometer to monitor temperature. I usually do no more than 8 birds per weekend. So far since last spring, this setup has been used for: 28 chickens, 1 duck, and a dozen or so quail.
