Found a baby fawn its so little how do i get permits to raise it, take of it, i live in illinois?

Dont do anything. Mother deers often leave their fawns alone for long periods of time and will come back to them. This is often out in the open hidden amongst vegetation . Only when it is clear that the faun is in trouble or it is clear there is no sign of the mother must any intervention occur. If this happens phone the nearest wildlife rescue centre and they will provide you with advice about what to do and will take care of the faun in its mothers place.
