I won't say something can't happen. But in parts of the country where the rut is in the fall, does normally cannot breed at a time that would yield a spotted fawn on 11/29. But, you saw what you saw. The yearling doe or the mature doe may have been the mother. It was obvioulsy a very late conception.

And for the record, bucks are physically capable of breeding year-round. Antlers have nothing to do with it.
