Fieldmice Nursery - in one of my vegetable beds!

I am curious whether the maternal instinct which has women cooing over kittens and puppies, extends to young field mice, or are they all jumping on chairs yelling, kill them, kill them?! I figure so long as they hang out in the fields and don't eat too many of our veggies, better there than in the attic! By the way if you feed birds, mice will be living only yards away from the bottom of the feeders...
