Without knowing specifics, the short answer is maybe. There could be a number of explanations for late fawning. There could be weather influences causing a late rut, buck/doe ratios could be off causing the breeding season to be extended, or just a few occurances of this making it look like there is a problem. In a perfect world, the primary breeding season will be confined to a week or so, but we don't live in a perfect world. I'd contact the local biologist and ask him. He may know more details to the cause in that area.
