To be honest, mice are very hard to hand raise, and it often does not turn out as we hope for it to. I would suggest keeping them warm and continue to try and feed them the milk you purchased, maybe offer it on your fingers, it may be the little bottle (if thats that you bought to feed them) they wont take- it dont smell like thier Mom or feel like her, the other thing you can do, is to get a small syringe and try feding that way, worse case senario- tube feedings, but you have to be very very careful, and really, if you have never done it is hard to explain to you how, if you have anyone that knows how, that is willing to show you, ask them... if we were close, I would show ya. Also, maybe try letting a piece of bread soak in it to soften, and see if they take any interest in it. Chances are, they were not weaned, and were in the process of being weaned.
