Im not incredibly educated in this subject but I just want to let you know you did everything correctly and what happened to your baby is not your fault. With the rats doing what they did to her I can think of two things, sometimes animals under extreme stress will eat things they shouldn‘t, like dogs or cats when their owner passes. It doesn’t take very long, sometimes within a day they will start eating them. It could also be the rats grieving process. Sometimes when cage mates die it is important to Leave the body with the rats and monitor them. Typically when a rat passes rats will do all sorts of things to the body to process they aren’t alive anymore. For example when one of my rats passed away my other rat started stomping on his brothers body and biting at it like crazy.
Im very sorry you have had such a traumatic experience so early on.
