are we starting with a mature pair and is there incest involved? ;)

assuming yes to both of the above as well as assuming maximal birth numbers and
survivor rates along with all female offspring and one very busy male...

my recommendation is to get rid of them as soon as possible... that or teach
that male about the practise of safe sex O:)

i believe i have the chart correct... maybe have neekha check my (and excel's)
figures? i'm considering "babies" as 0th month of maturity, "not_mature" as 1st
month of maturity, "females" as at least 2 months of maturity... this gives you
the "mature in 2 and have 12 each month after" scenerio...

you'll notice that the "females" column doesn't start increasing until the
first litter is 2 months old... the flow is "babies"->"not_mature"->"females"
and once they get into the "females" column, they immediately have 12 per...

this is not taking into account that the gestation period is 18 to 20 days...
we're assuming a uniform "month" period...

at any case, i'd hazard a guess that by the end of April, your aquairum or cage
is not gonna be large enough to hold them all ;)

surprising enough, i was also able to locate this recipe in my MM-BIG database
of 65492 recipes... but i don't think it'll help you with your crop abundance

MMMMM----- Recipe via Meal-Master (tm) v8.06
 
      Title: Fieldmouse Pie
 Categories: Entree, Casserole
      Yield: 1 Dish
 
      5    Fat fieldmice
      1 c  Macaroni
    1/2 md Onion, thinly sliced
      1 md Can tomatoes
      1 c  Cracker crumbs
 
  Boil macaroni ten minutes.  While it is cooking, fry out fieldmice
  long enough to render out excess fat.  Grease casserole with some of
  the fat and put a layer of macaroni in it.  Add onion, tomato, then
  salt and pepper it well.  Add fieldmice and cover with remaining
  macaroni. Sprinkle the top with cracker crumbs seasoned with salt,
  pepper, and butter. Bake at 325 F for 20 minutes or until mice are
  well done.
  
  In cold or rainy weather when mice are hard to find, you may
  substitute sausages. MMed by Dave Sacerdote
