First 3 are from the same buck, and last three I am mostly interested in the deer with the bent brow tine.... I am horrible at aging.
The first one I would say at least 3 1/2 but the second one is tough because of the angle. If I had to guess I would say 2 1/2.
The broadside pic made me think 4.5 but the others lead me to be closer to 2.5-3.5 I will go with the mean and say he is 3.
First buck during hunting season will be 4 1/2 years old. The second buck in question is 3 1/2 years old during hunting season.
