Do you guys every have an aggressive male rat, and what do you do with it?
Should I feed it off because I don't need any aggressive traits to be passed along.?
I have a large male who is well over 300g. And no matter who I house him with, he beats the other rats up. He will leave bites on the necks and backs of any other male he is housed with, even others that he grew up with from the same litter.
Right now 6 of my males are recovering from attacks from the special male.
Opinions?
