Help! We had two rabbits, one male and one female, and they just had a litter 2 months ago. Five babies, they're all healthy and growing well. I just went out to the hutch today and there are four new dead newborns in the cage. I'm completely baffled. The male rabbit has been separated from the female since before the first litter was born. The babies aren't old enough to mate, and the mama hasn't been with daddy for over two months. What's going on here??? Where did these new babies come from?

Um...is it possible a wild buck got to her? Are the protective walls on the hutch screening or bars?
