Well... this morning I ended up removing one of the males like suggested
However I was a little late before there was any damage.
I noticed yesterday that Patch the Black and White mouse was awake all day eating and running the wheel, I joked that he was pumping up to be the boss, well I was right, this morning I saw him chasing after Austin the Orange and White mouse and he had actually chewed off one of his balls
So I removed him this morning and figured I'll let Patch have his Herem, and we'll keep Austin as a pet, I have him set up in an empty lego box for now, but when the husband gets home were going to buy him a fun little mousie habitat.
I switched the bedding of my breeder mice to pine and hay mix and it smells OH so much nicer!
Next... the wait for some little pinkies to start dropping
