So these little ladies are just pet shop mice bred from feeder stock, the lady also keeps black and tan fancy mice though. I couldn't locate a breeder near me. I just got them this morning. 
The little black and tan one is really active and has been running around the cage exploring everything, building a nest and testing how chewable everything is. The other one seems fatter and lazy - she didn't seem too bothered about exploring and just curled up in the floor substrate and went to sleep. I'm hoping this is normal? I'll keep a watch on her anyway. Also, I appreciate that these are far from show mice but I was wondering what colour the one in the bottom photo would be considered? That is if she's a standard colour at all. She's also lighter than how she appears in the picture.
(Also, sorry for the poor quality, my camera broke so had to use my phone.)
