Dear, are you certain he's not simply teaching her to survive? I know that she's your daughter, but teaching her to hunt and feed safely will keep her healthy longer and ensure that she is able to, should she chose to feed when she gets older, be as safe as possible when she does it.
Please don't get me wrong, however. I don't mean to say he should have done so without discussing the matter with you. You are her mother, and the two of you should be able to talk about what's best for your daughter. Sadly, there's nothing to be done about endangering your daughter. To hunt is something we are all taught at some point or forced to figure out. I wish you luck when dealing with her father.
