Duck, I was visited by about 6 deer this morning as I watched them from inside the kabin here. Sometimetimes its tough to tell the diff, but the're just like people, they have certain characteristics that are different from all others, but look at detail in each deer. I noticed this doe with 2 yearlings from last year this morning and the yearlings look almost identical and almost the size of the doe, but I noticed that one of the yearlings had exceptionally large and dark tarsal glands that were much different the the others, not sure yet, but maybe a buck. The thing to do is pick something out on that deer that you'll notice the next time, DETAIL, look for it, its like a fingerprint. Good Luck, Bobby
