If Your allowed to shoot another Buck in Your State go for it since You have so many,once the Rut kicks in most Bucks will disperse looking for their own area/territory and search for Does.....as mentioned a little thinning out on Bucks and letting the Doe's alone to reproduce is a good idea!
Taking out Bucks with undesirable Racks or deformed Antlers is a good idea or a Buck with a poor looking rack after 2 or 3 years old is probably not going to get much better?
