We raised up a baby groundhog to near adulthood and then set her free when she was old enough to live on her own. Then a few months ago, my son brings home 2 duck eggs that he rescued when he found other kids throwing the eggs out into the middle of the pond. I didn't think there would be much we could do for them but we kept them warm and, much to my amazement, 2 days later, they hatched (I am still heartbroken about the eggs that got thrown into the water...how horrible!).

We kept them for a couple of weeks but eventually got a sanctuary to take them in, that was going to try and introduce them to the wild and, if this was impossible (ducks imprint on the first thing they see), they would give them a safe forever home.
