RE: Shouldn't they be bigger?
I agree with what most have said -
Especially that you cannot evaluate 1.5 year old deer for potential on your hunting property -
Especially since most 1.5 year old deer re-locate in the summer of their "1st rack". Usually more than 5 miles away. Its nature's way that deer do not interbreed signifigantly, so while that spike may well be a fawn you saw last year - odds are that he will relocate away from your hunting property - usually about the time their velvet is shed.
A small % stick around -but there is also an "influx" of new 1.5 year old bucks passing through and looking for a place to call home.
