I've been looking into starting a small colony of rats. I was planning on removing the male to give females a break period and to slow their breeding down a bit. How hard is it to reintroduce a male to say 2 females in a tank? or would it be better to intro females to his tank one at a time? If that is the case how hard would it be to put females back together? I might need 3 females need to sit down and figure out the averages to allow the mothers a little break, but ya'll should get my general question on being able to seperate and reintro them. Thanks
