Yesterday I tried putting together my first mouse colony, 1 male with 7 random females in a mixing tub. This morning i witnessed a little bit of squabbling between the male and some of the females and theres dried blood on one of the cardboard tubes.
I'm positive the females are female. I've heard mouse colonies are one of those things you set and forget. My question is do I let them settle thier diffrences themselves and replace the male if and when he gets killed or do I try to replace him now?
