how many "decent" bucks will live in a single area. today there was 3 bucks taken from my #1 spot and 4 from my #2.......on average how many shooter bucks will inhibit an area?

That depends on several issues....
#1. How big is your spot?
#2. Bucks tend to travel more especially right now!
#3. How is the dinner table?
#4. What is the buck to doe ratio?
#5. How much pressure does it get?
#6. What do you consider a quality buck?

I am sure there a some more I could come up with but my back straps are ready so I must tend to those.......not does!
