I have seen a couple of spikes that were in the 2 1/2 to 3 1/2 age bracket. This is very rare and these bucks have very little chance of ever having a large rack unless the lack of nutrition is the cause which is highly unlikely. Generally a spike is just a yearling buck and body shape and size will indicate that. I would pass on them unless you can determine that it is a mature buck. Give them a few years and you will have some wall hangers.
