I have been trying to create a cow farm with spawners, I saw that passive mob should only spawn in grass but they are spawning in the air, is there any way they only spawn in grass.

Sorry for any mistakes english it's not my first language.

I'm fairly sure they should only spawn on the grass. How are they spawning in the air, on some kind of block or just in the middle of nowhere?
