iv got a question. will mice "do to deed" when the female is only in heat(i think that is the right word for it) or will it happen even if the female is not. the reason im asking is i got a another pair of breeders same set up 1 male 2 females and their is just nothing happening. their not fighting or anything now with my other set of breeders it seems like its ALL THE TIME he will literally get something to eat drink a little water and get back at it. i am working 3rd shift my wife is the one that watches them and tell me everything they do lol (she has them all named already)... any help is always appreciated thank you
