I spoke with an enforcement officer in my area as I too was doing the same. he was satisfied with a few pics of the animal and the boned carcass. THAT DOES NOT MEAN IT IS OK WITH EVERY OFFICER, just what I found. he told me the big concern was animals with 3 hamstrings and 4 backstraps and cows shot on general tags. it might pay to ask the enforcement guy in your area if he would cut you the same slack. otherwise, you need evidence of sex.....as mentioned above.
