Loved raising Turkeys, haven't done it this year as I've been too busy with other stuff and really miss them around the place. We usually do about 15 for Xmas, last year they all ended up roosting in one of our trees and snubbing their shed and I let them (rightly or wrongly) free range with my chickens - I think that's a question of space and how much you can dedicate to them. Mine have ten acres to roam over, the fact that they choose to stay in an area only 1/4 acre is their own doing although we did take them for walks around the fields.
Mine were Norfolk blacks, fed on a decent feed and made 7-9 Kg (hens) and 11 - 16 Kg (Stags)
