One of the female rats assaulted the male for a raisin, bit him pretty hard, too and drew some blood on his back. He's sitting in the corner shivering and I wiped him with some water and put a dab of neosporin on him, nothing serious. He's fine aside from hiding in the side of the tub and gets really defensive when she comes by (stands with his hands up, shivers more, and presses against the wall turning his head away). She also tried biting my finger, I was pushing the two females away when they would make little test nips, but she tried to give a real nip. The male just licks my hand and the other female learned really fast not to (even with only a couple little light nudges) but she just kept trying to bite harder.

What do I do with her? Put her in time out or what?
