Caring for the babies
Checking The Babies
Baby mice have very translucent skin; practically transparent. You will be able to see the cracks between the plates of their skulls, their stomachs when they are full of milk, the veins on their toes and all sorts of things. The milk is a good thing to watch out for. Since there is very little we breeders can do to make sure everything is going ok, aside from giving the right food and letting mum do her thing, it is nice to be able to check up on them and see that they've been eating. Don't worry if you can't see it, mice have a pretty fast metabolism and they probably just haven't eaten for a while. Check back in an hour or so, after the mum has had a chance to feed them. Often very large and very small litters will 'fail to thrive' due to, respectively, a lack of milk to go around and not enough stimulation to keep the female lactating plentifully. This is ok; they may just wean later and be runts.

You can see here how runts look less developed than 'normal' pups and they are also usually behind in achieving developmental stages, including pigmentation and opening their eyes. Both pups above are 3 days old. The pup on the right is a lot bigger and no longer looks like a newborn, unlike the runt.
Diet For Baby Mice
Once your young mice are separated and they are on solid food, they are ready to go to their new homes. Remember that mice are much happier when in groups so if you have someone who wants to purchase a mouse from you be sure that they will be in a group. Also keep in mind that male mice are better introduced while young or when in the same litter.
