Here in lower Michigan on the properties I hunt, the deer are overpopulated. I agree people here that a fawn (IMHO) has spots. In the late season when the spots are gone, we consider them yearlings. Anything with spots is never shot. The yearling does we try and take out of the heard. The button bucks are always given a free pass. The meat is very tender like eating butter.
We also take out any does unless they have a button buck with them. Hopefully, the button buck will stay with the doe longer and have a better chance for old age. Might just be wishfull thinking though. Unless the buck you shoot is worth mounting or has bad genetics, we pass on our lands. To many does here to start shooting 1.5 year old bucks.
