So I have a few questions regarding my future growout cages. As I said in another thread i got 3 mice colonies, 3 cages with 1.5 in each. I also have 2 empty cages that will be used for weanlings to grow up to size in, one for females and one for males.

My questions are these; Let's say I have 10 females in the growout cage, another litter is ready to be weened. How do I place them in the same cage as the other 10 without causing alot of territorial battles? Do I clean the cage before adding them all, both the original 10 and the new litter?

I'm just starting with my mice breeding so any advice are very welcome.

Thanks
