Unless the person in this picture is a wildlife rehabber and the mother bunny is definitely dead, this is a very, very bad picture. A wild rabbit that young is NOT old enough to be away from Mom, and every year you get a bunch of well-meaning but ignorant people who don’t know that if you find baby bunnies in the wild, they’ve probably just been left there for the day by the mother rabbit, who will be back soon. Also, rabbits don’t do well even with professional care; they’re very sensitive, and formula isn’t enough for them to thrive a lot of the time (for one thing, they need to eat their mother’s fecal matter to gain important immune system boosters and nutrients—seriously!)
If you aren’t sure whether a nest of baby rabbits has been abandoned or not, put a ring of flour around them, then come back the same time the next day. if the flour has been disturbed, then the mother has been back. If the rabbits are abandoned, then they need to go to a wildlife rehab, not a cardboard box in your garage.
