Well i don't think it really matter either way there scientific evidence to support what others have said and just because the doe is by her self don't mean a thing. One of the guys i work with said he has a doe that beds her fawn down on a regular basis just outside his fence underneath a tree and leaves for hours. He even said he can walk up to the fence and the fawn just looks at him. So just cause she's by herself don't mean a thing. Here's some pics of a doe and her fawns frequenting my feeder i'll leave them alone as there are some bigger more mature does i can take if i choose to.
