4 of my 6 female mice have delivered in the last 11 days. I took these pictures last week of 2 preggos and 2 with babies. The dad is solid chocolate, and the moms are 2 albino, 2 solid tan/gray and 2 w/ patterns. The oldest babies started to come out of the nest and explore today. The pregnant girls gave birth 2 & 3 days ago.
