Okay so as you all know i intro'd 2 groups of 2 girls into one big cage. Bino is doing the normal, bum sniffing and mounting to show whos boss, whats expected. She has taken very well to her mini me (Rudolph). Anyway the girl Lou who was previously being bullied is now bullying one of the babies. Shes not just doing the normal mousy stuff like Bino but attacking poor little Jingle. I also think this is what happened before. She attacked Danger Mouse but as she was smaller she got beat up. I think Lou chooses one mouse from each group and really bullies them. I've seperated Lou into her own cage just now whilst i get some help. Should i try and into the two older girls back into the group and leave Lou on her own? Or do i pair Lou with Bino? (They get on okay, they have little fights but not as bad as any others she's been in) Or any other ideas? Any help would be much appreciated Edit: Now Bino is doing the same to poor little Jingle but not to Rudolph ??
