A yearling is a deer that was born this year. There is no question about that. Most hunters have a hard time telling a yearling buck from a doe. Unless they know what they are looking at. A 6pt is usually a 1.5 year old deer. Its all about the genectics. I have never seen a spike or fork yearling. If I ever seen a spike or fork yearling I would say that buck will be a trophy at 3.5 years of age. In my 29 years of hunting Ive never seen a spike or fork yearling. I think your confusing a yearling with a 1.5 year old deer...
