Weird Question about mice?

hi i have bred mice for a long long time maybe i can help. The best way to breed mice is with a set up of 1 male and 5 females in every cage. However even though this is the -best- setup it does not seem to be the right setup for you. I suggest that you keep your groups at a limit of one male and 3 females at most. Only use these cages for the breeding. Once a female has become noticably pregnant i suggest that you move her into a cage specifically for pregnant female mice. This way no males or non pregnant females can kill the babies. This will also increase your odds of the babies surviving because typically mice only eat their babies when they are stressed and male mice get stressed by being around pregnant female mice, as do non pregnant mice (not usually but sometimes) and when they are housed with pregos then they sometimes become so stressed that they kill the babies. One more point is that to breed mice succesfully you MUST have temps within five degrees of 77 and you must have at least 8 hours of light in the room they are in (this tricks their bodies into thinking they are outside so they breed). So overall keep the pregos in their own container, maintain temps to be near 77 degrees and allow them to have reasonable hours of light and dark times throughout the day. Good luck
