So today at work I was looking through our new feeder mice that we got in and I spotted a very VERY sweet looking chinchilla colored mouse with a little black spot near her rump. I snatched her up praying it was a female and it was. Before I brought her home I was examining her and she looks slightly plump but not to much. Im hoping shes not pregnant because shes small. I put her in her own cage so I'll wait a couple weeks to see if shes pregnant to introduce her to my other females. If she ends up getting plumper what can I do for her since shes so young? Anything at all? Shes on my homemade mix already. Should I add some kitten powder milk replacer to her food or give her more dog kibble? Much advice needed
