I went to the feed store to buy a rat. while i was waiting, I was looking at the mice and a bunch of them ganged up on one and started eating it while it was still alive.
I told the worker there and he quickly disposed of the mouse. They usually have good husbandry there, but my question is why do mice eat each other like that. there was like 15 medium size mice in a 20 long. fresh water and a variety of food.
It was amazing how quickly they devoured the mouse, he was kinda still kicking when they removed him, but his lower half was almost all bone.
