Answer
You will need to make sure you keep the male and female separated from now on, so that you don't get unexpected litters. it takes 29=32 days to have babies. they pull big tufts of fur to line their nesting box with when having babies. you will need to provide her with a wooded or metal nesting box filled with hay to have them in. www.islandgems.net/palpating.html gives reference to how to check and see if a doe is pregnant.
As for colors of the babies you can have all kinds of colors depending on what colors the parents of the two you have and also the grand parents.
