Another thing to consider....are You letting the Bucks mature and get older and bigger racks?You also need to let the Bucks grow to Maturity,Younger Bucks will show their selfs more while older smarter Bucks will stay hidden,move more at night and be a lot more cautious!If You have too many Bucks they will disperse and find their own area too!
Once colder weather sets in You'll see more Bucks moving,making rubs and scrapes also....if You have Does the Bucks will be looking for them eventually.Im thinking the ratio of 1 Buck to 2 Does is ideal in a good managed area?
