Go to Elwynn.
Make a macro:
Put this on a keybound button.
Mount up, run along the edges of the water ways (avoid the murlocks.. as a guildie mentioned.. obviously murlocs eat turkeys because no turkeys spawned near the murloc village) and slightly off the road. Anyway.. Run.. spam the macro. When you target a turkey run towards it and continue to spam the macro. When you get close enough the /cast corruption will dismount you. When the turkey runs towards you, stab him with your steely knife. Loot turkey.
At ~midnight PST I got Turkinator after killing 43 turkeys. Any easier and they’d’ve just jumped into my bags.
