ballet!!!...., you spelt "u" wrong, it's Y O U, moron. Don't be so picky about someone's spelling and just answer the question.
Anyway, it's not always easy to sex male mice, especially before they are 4 weeks old. Male mice readily suck up their testicles when they are nervous, and to me, I'm used to sexing rats, their littles bodies are too small for me to be 100% positive.
A relaxed male mouse will show it's testicles when it is 3 weeks old and will be ready to mate by the time he is 5 weeks old.
Appologies if this is not what you meant by "pet baby mice to fully develope". You might have been asking for something different, like developement from conception to birth? Or what they look like as they grow up from birth to whenever?

Not long at all..about three to four weeks. A friend of mine took care of baby mice when their mother fell victim to a trap.
