All ingredients share the same spawn points. You just have to get lucky.
My results after finishing farming enough for 1 craft are:
4x Joint Part Meat
7x Fatty Part
10x Lean Meat Chunk
Respawn seems to be about 5 minutes (not timed, just feeling). There seems to be a max on how many "preys" are spawned at any given time, cuz i couldn't reliably find them in the same spot.
