We saw one the day before rifle season opened that we guessed to be no more then a month to month and a half old. We are guessing she would have had to be bred in April or May. The hardest part for this would be to find the buck that was still fertile. They are only fertile when their horns are on. Sure you see one here and there with a rack still in April or may, but its rare. Sure wouldn't have been a crowd around her lol.
