Honestly the best place is beetles. You're right there next to the cows so when you need to change them it's not going to be more of a hassle than it already is. Also the mobs are constant so there's no need to sit and wait for wind mobs to spawn.
A close-ish place I used to use was the Wind Bee's located south of the farm, left side of the mountain range, lower part of south island. Have to go through a lot of mobs though to get there. I still vote for beetles. Why fix what ain't broken, ya know?
