So I recently started a breeding colony with one male and four females in a 10 gallon tank. Three of the females became pregnant and the first one gave birth to her litter yesterday. However, she ate the entire litter within the first day. I had the male and the non-pregnant female in a separate enclosure, and she was in the tank with the two other pregnant females. After I noticed that she was eating her litter, I looked in and saw one of the other pregnant females joining her in eating a pinkie. I then decided to remove the third pregnant female and put her in a separate enclosure. I peeked into the room this morning and saw that she had given birth, but was disappointed to see that there were two pinkies in one corner of the cage, another at the opposite corner, and one just inside the entrance to the hide. Does this mean that she is rejecting the litter and won't care for them? Don't they need to be huddled together in the nest for warmth? Things were going so well and now the results are turning out pretty poorly. And advice or comments from successful mice breeders?
