I haven't seen a property where I remember every of age doe having fawns, or at least most, since the 90s. I live on 150 acres. We don't kill does and average 1-2 bucks a year. We are far from over populated, yet of the 5 does i see regularly 2 have fawns. One has twins the other has a single. One un bred looks like she may only be a year old so maybe she wasn't old enough to be bred last year but the other 2 were. So based on my very minimal data only half my does had fawns. Oh and i run allot of cameras here normally. I see bucks day to day on this property that have never been on a trail camera.
