a bit more experienced. We used to worry about that, as well, but in photos of the fawns (we had twins and triplets several times), you could see her back in the trees. In person, you really have to concentrate, but she's undoubtedly there.
I have a timber behind me and beyond the fence is tall grass and trees. If I sit and watch the entire scene, I can see the grass move and if I concentrate, I can see the doe's nose and eyes. After she is sure everything is OK, she will move out into the open. They are clever in their camouflage. They keep near the fawns long after the spots are gone. I have 16 does that come to my yard and they bring their fawns/yearlings with them...most of mine stay with them in the first year. Kind of like mother and daughters out shopping together. The youngsters are very polite to their mothers. It's fun to watch. In the winter, I feed them cracked corn and the young ones will stand back and let the mother eat first and then they step in. Not so much with the bucks. They are bullies and rough with the young ones.
