I think the first buck could very possibly be a healthy 2 1/2 year buck, I have seen them in certain areas in PA @ 2 1/2 years that looked like that. I don't think he is older than 3 1/2 years though at most. The bottom pic is definately a different buck in my opinion, look at the placement of the browtine on the left......that also looks like a 3 1/2 year buck.
