We have had an earn-a-buck deer management program for the last 4-5 years here in my hunting unit here in Wisconsin. What this means is that if you want the opportunity to shoot a buck you must have killed an anterless deer. The tag is good for the season you shoot the deer in and the following season, so if you don't harvest a anterless deer in the season you can't take a poke at a buck.

That being said, in the first few years that this program was implemented, it wasn't that hard to get a non-fawn doe. But due to the large numbers of hunters (earn-a-buck carries over to gun hunting also, so if you want to shoot a buck during bow and gun you need to shoot two does) in the state, the doe population in our area has taken a large hit.

I have yet to run into a situation where I have been unable to harvest a yearling doe (or older), but there have been a few situations (seasons) where if I was sure I was not shooting at a nubbin buck, I would shoot a doe fawn.
