I'm thinking of breeding some mice. I dont have a huge number of herps but that number will be growing in the next 6months or so and breeding would also make supplying fresh killed for fussy feeders much easier. I have done some research and it says its best to use 1 male to 2-4females. Should the male be removed or the females separated before/upon the birth of their young or are they fone just left in a group?
