Ok. I think we have identified one problem. A medium mouse once a week for a 3 year old BP is underfed. He should be on small rats. I would try and up his prey size, make sure you aren’t handling at him too much and then see what happens. If he’s 3 and you changed his set up around dramatically and decreased his prey size that could account for some of the aggression. Maybe also try to see how he was housed before and start over.

This is great advice here. He is hungry so his instinct is to hunt and strike warm things. Mice are to small for adults.
