The mother will not come back. In fact when I found a pack of em near the fence outside my window and left em there I heard the mother KILLING yes KILLING them. Why? I don't know. But some of em were dead the next morning. Also the fact that you touched them does not help at all cuz with some animals like squirrels, if they have human scent on them, the rest kill them. Again WHY? I don't know. Nature can be pretty mean.
