I found a vulture nest in a very small cave in my public land turkey spot last year. It was just after spring squirrel opened and I was squirrel poppin with a friend and found a cave and crawled in. Cave had 2 openings and nearing the exit I found a fresh hatched vulture hissing/growling and another egg with the baby pecking a hole in it. When I came out of the cave my friend had seen a big vulture fly out the other end when I went in. Strangely I did not smell anything bad that I can remember.
