I wrapped mine in plastic wrap, then put them in a garbage bag and taped it tight w/ duct tape. Not very pretty, but I didn't know what else to do either...
If it is big enough, I guy a 2 mill plastic drop cloth, cut a square large enough, put the turkey in the middle of it, bring the edges of the plastic together, spin, and tie it off. That's what I did with my 40 pounders and up.
