Most of you are pretty close.
Here are the ages that were given to my by WDFW.
1. 2.5
2. 4.5
3. 4.5
It was interesting to me that the 4.5 year old boar and sow were almost 50% different in weight and that the 1st and 3rd were two years apart in age but the same weight.
I will see if I can did up some more pics of bears that I have age data for in a day or so.
