Just because fawns still have spots doesnt necessarily mean that they have not been weened off by the mother. And it definitely does not mean they are not capable of surviving on their own yet. Its september and unless those fawns were born extremely late they should be more than capable of making it on their own by now. If they were born late they very possibly will have trouble makin it through winter. (that is if you are somewhere where there is snowy winters). Each persons concious is different in cases like this. Imo the fawns ability to survive without mommy by this time is not an issue tho.
