I would like to hear your opinions and some advice on my problem.
I have 4 female mice, 2 are my older girls and the other 2 are mother and daughter. I started the introductions of both groups and 2 weeks ago I was able to put them together in the same cage. Once in a while they would argue about who's the boss, but there was't any blood or real wounds, and in the last week things have been more peaceful.
The problem is that now 2 of the girls (one of the old and the mother) decided to fight, and fight for real. After some separations and reunions I found that the mother was the one causing trouble with the others so now she is in a different temporary cage.
My plan is to make a division on the big cage so I can have all the girls living there without fights (the cage is big enough for that, it's a Savic Zeno 2).
I would like to know your opinion. And Do you think I will be able to reintroduce the mother to the others in the future?
