Last night they were all fine. All were playing on there wheel. Well.... Just a few mins ago I went to feed and change there water like always And...... All but 3 of the babies were laying there. 2 mamas and 10 babies. 1 head looked as if it was eaten off. 1 belly looked black. Idk. I'm horrified!!!!! Took the 3 babies out and put in different container. What happen!?
