I always try to shoot a doe that has a button buck for a fawn. Theoretically, the buck fawn should stay in that area and make it his core area for the rest of his llife. A lot of people will say that this will encourage inbreeding. Doubtful in my opinion. You just killed it's mother so he would have to breed to grandma or sis. And the odds are that they had different fathers than the young button buck. Besides, inbreeding takes place all of the time in the animal world.
