RE: Question about a fawn?
A new born fawn has no scent, So the mother lets the fawn lay by its self so her scent does not attract any predators, she will meet with it to feed it then when she feels it is ready it will follow and stay with her.
The fawn you picked up will be fine, The mother will take it back. My kids find them all the time pet them for awhile then leave them and the mother always comes back. 2 years ago we found 2 that the mother just gave birth too and one was deformed, The mouth went way too far back past where the tongue goes down the neck, we left them there and went back awhile later and the mother only took the non deformed one, the other was not even cleaned off so I put it down.
