we do it a little different where I hunt since the older does throw twins or more we try not to shoot the big does. and were not the only ones that do it. its seemed to work pretty good so far a 17 and 14 point were killed by the landowner.my friend killed a 19 point and 2 nice 8 points. another guy that hunts on the same land killed a 11 and 12 point. and last year I killed a nice 140 class 10 point. and the herd seems to be doing great. weve noticed our neighbors doing the same thing letting the big does go so they will throw more babys next year. not saying other ways dont work thats just my thoughts on the subject
