Is she attacking them or just pecking at them? Momma's decide when they want there babies to go, and they can be pretty forceful about it.

What breed are they?

she just attacks when they r close to her or sees them eating

If she was separated for more than a day, she may have decided they were no longer part of the flock, and is reacting aggressively because of that.
