So this is my first time running into a problem like this and hopefully some of you rat experts can give some insight. My best breeder male has been with a smaller male hanging out for a few weeks. I hear all kinds of screeching come from their tub tonight and when I check, he has a bunch of bite markes on his neck and back. Not bad, barely any bleeding. I left them together and listened for a few more minutes and it started up again. I think its the big boy doing the screeching. So I put him down with my two big Albino males that are just easy going. A few minutes later I hear running around and screeching in that tub. I can't figure out whether its him causing problems or if he seems weak and the others are picking on him. He seems very unsettled and flighty which is weird for him. Any thoughts?
