I don't have a lot of fawns this year either. I do have a lot of very young does. Deer that were sub 80 lbs in the spring. On the one hunt I have been on, I saw 9 does and there was one fawn.
From what I can tell from my cameras, I have a verified 3-4 different fawns. I definitely have coyotes, but nothing that appears abnormal.
This is a new to me place and the nutrition was basically nonexistent. It will take some time to reverse that and get the herd health in check.
