Never seen this before.
I killed a doe this morning that weighed about 100 pounds. Field dressed her and everything looked fine. About 10 minutes after I finished I was cleaning up and getting ready to load her in the truck when I looked down and saw her intestines moving like a pile of snakes rolling around on each other. I am not a surgeon (LOL) so I don't know exactly which part of her guts it was but I am guessing what I would call the small intestines. About 1/2 inch in diameter and gray in color. The hole pile was pulsating a moving around like it was full of bugs or something. I cut into them in a few places to make sure there was not some kind of bugs. I took a short video on my phone but I don't think you can upload videos on this forum can you?. The video is a .mov file from my iPhone. Anyone ever seen this before. I have probably killed and gutted 50-75 deer in my life and have not noticed anything like this before.
