I know a guy who owns four different parcels from 12 to 65 acres, and one parcel that is 250 acres. He is strictly a big buck hunter. He lives on the 250. He has one foodplot on each of the other parcels with the exception of the 65 acres, where he has two. All the smaller parcels have clover plots and drilled wheat into those same plots in the fall. He pays someone to spray, bush hog when needed, and plant the others. He doesnt move any equipment back and forth. When speaking of a big buck, I live in the south AR pineywoods and a good buck is a 130 and a big buck is a 140. Anything over 150 is a monster here. He hunts for 140 or better. He told me he had killed more big deer off his 12 acre property than his 250 acre property. I dont doubt that at all.
When I started, I bought 12 acres and built a cabin on one end and a food plot on another. I have kept buying property and now have about 300 acres in one spot. I had almost as many big bucks visit that 12 acres as I now do my 300. And it was a lot easier to kill them, because they were visiting one food plot as opposed to ten, now. I have ten mounted deer heads - four came off my 300 acres, five came off my 62 acres, and one off nearby public.
I drive my 65 hp tractor to my 62 acres and it takes exactly 30 minutes. I trailer my smaller tractor. I dont like moving equipment.
With smaller properties, like my 300 acres and down - i believe I am mostly attracting deer and not so much growing them. I am basically trying to get the bigger bucks within a one mile or so distance, to spend more time on my land. I dont think there are many more bucks within a mile of a 300 acre property than a 40 acre property.
That said, outside influences off the property can make a huge difference. Adjacent hunters, habitat quality, management practices and regulations and restrictions in the area, etc.
No doubt, a larger tract is much easier to work than a bunch of small tracts, but no way can a larger tract be within reach of as many big bucks as multiple smaller tracts
