Can you help me get pregnant?

Question
Hi Natasha,

Thanks for taking my question.  Proud colony owner of thirteen mice here, recently acquired from a breeder and other sources in the last two months.  Everyone is healthy and youthful, vigorous and developed, but absolutely nobody is breeding.  I have four bucks, each of whom has at least two does (or more!) to himself.  Problem?  Nobody is getting pregnant, at least no one has yet.  I have been taking weights regularly, and all females are the same weight as when they were acquired.  

Do you have any tips on what I can do to get the proverbial party started around here?

Thanks so much,

DJ

Answer
Hi Daniel,

How about some soft music?

I have to say i don't know. However, the bucks are happy to have friends

I hope you are not breeding feeders..... live feeding is not only terribly cruel to the mice; also snakes are often killed by mice. They may go to sleep and the mouse attacks. I'm not kidding. I recommend against this.

Sorry this took so long! I was not getting  my notifications.

Good luck!

Natasha
