Ok. So I walked in on this situation, therefore, there are many possibilities as to what transpired before I arrived.

When I went to check on my ASF colonies I saw that my newest breeding group finally had a litter. Upon closer inspection there was one alive and one chewed completely in half. Just in case, I removed the live baby and placed it in another colony. I then snapped this picture to show you all. I know I've been asking if ASF's eat babies for some time now. And here is the proof. The bottom half of the body was completely gone.
