I also slowly warmed them up before feeding them-they both were slightly skinny-I did not want to wait a week before seeing if they would eat.
In my opinion Ben might be right and what happened was probably that feed rot in the stomach. Even if you warmed them up before feeding there was probably not enough time for the enzymatic systems to kick in full gear. Just MHO.
Maybe you will be able to find something different after the necropsy.
Thanks.
