Spikes must comprise a good percentage of your yearling bucks then.
Differences in deer genetics are always interesting. In my area, I rarely see true spike bucks (no other points) either in the woods or hanging on meat poles. Most yearlings here are sporting 4 - 8 point small basket racks already.
In SE Minnesota the DNR has implemented point restrictions - 4 on one side - and expects that protects 70% of yearlings. That would generally equate to about 1/3 of yearlings being 7 or 8 pointers already as a 1 x 4 or 2x4 would be pretty rare.
