Agressive Male Russian

My russians are out of hibernation and the males have one thing on their mind! I have 2 males and 3 females (all full grown). One male in particular, is EXTREMElY aggressive and targets only one female. She has taken on many injuries (mostly losing scales on her front legs). Yesterday, he bit her beak harshly. Her two nostril holes are no longer visible. Can she still breath? She isn't breathing through her mouth so she must be able to but I can't see the holes. I have separted him in another enclosure for now to give her time to heal. Is she in danger?
