I don't know if "notorious" is the right word--if you're going for egg production only, and don't want the hens to hatch chicks, it's a great thing.
When hens go broody and start to want to sit on eggs, they can stop laying. Broody hens aren't a good thing in a laying flock with no roosters, like mine! Instead of non-setter you might also hear "not broody."
