I say with only 200 acres and a 5 yr lease you need to limit the number of bucks to one per hunter and to greatly thin down the doe numbers,I believe you said the first time you hunted your stand you saw 21 does and 3 bucks,thats a 7 to 1 ratio ,that's your problem right there and thats just the does you saw.Thin the does and limit the bucks then reevaluate in 3 years and see where your at with your buck numbers and size according to sightings,trail cams ,ect.You will see more bucks if you get rid of some of those does,does will push the bucks out.
