I've recently decided to try my hand at breeding mice... I have one female that's a bit older, and yesterday I picked up another female and a male, who are both younger (and smaller) than my older female. Can I keep these 3 together, or would it be best to wait until the younger 2 are a bit bigger before putting them together? I'm worried about the bigger female picking on the younger 2... At the petstore they had smaller & larger mice in together and they seemed to be getting along ok, but when I had these 3 together in a tub for a few minutes my bigger female started going after the younger 2 (especially the younger female), so I'm not sure if this is just something that they have to go through to establish a pecking order, or if I should be worried about the bigger female actually hurting the younger 2.
Thanks for any input you can give
