When I was a kid, the guy down the road had raised a fawn and it would do that kind of stuff, they even let it in the house. One year it even had twins but it wouldn't stick around much after that. It would bring it's fawns back every spring and bed them there in the yard. Soon the fawns brought their fawns and bed them in the yard. They ended up with deer around the house all the time, except november. It was pretty neat when I was a kid, the old man died and his wife got put in a nursing home. The kids sold the house and the new people said they couldn't afford feeding them all the time, so they quit coming after a few years. I have wanted to raise one every since, but have decided it's best I don't.
