Are these mice safe to feed?

[Awaiting Abyss]

I recently rescued a mother mouse from a pet store that was continuously breeding her... They normally get in only female mice, but they must have accidentally gotten in males because she was in with two males.
So I brought home her and all five of her current babies. The five babies are doing well, and the momma had her last litter of seven babies. They were all healthy and fat, but the mother got stressed (and it may have also been because of a smell... it happened right after a wild mouse came into my home) and killed all seven of the babies. I found them right after it happened.. some were still barely alive.. (not sure if they were really barely alive or their bodies were just twitching) :/ ..I put them all in the freezer so that I could ask this question and to kill the ones that may have been barely alive. They were just past the point of getting fuzz.

Now.. for my question. Is it safe to feed these babies to a snake? They were healthy when they died; just killed by the mother.
