Rios/Merriam's/Gould's/Osceola\Silvestris\(not to mention Broad Breasted and Heritage Varieties) are, excepting specializations, owing to natural (and `unnatural') selection, pretty much the same `bird' (genetically speaking). `Docility' is, in part, a measure of one's familiarity with the turkey's behavior (visitors might think toms are going to stomping strut them to death, the owner knows better), the temperament of the individual turkey (most are easy going, however a few are not - `Meleagris Gallopavo Sandwichis') and that temperament is colored by hormone levels (to some extent - more so during breeding season).
If any of the above (excepting the ones that need eating) imprint on you and associate you with food/safety (these guys are Very Much creatures of habit); you'll be keeping them in the run when you work in the garden, do minor repairs outside with small handtools, etc. as you will be surrounded by extremely nosy, tool throwing, tomato and berry thieving turks.
