I agree with the above. I killed a 82 lb field dressed doe last year on a quota hunt and it was aged at 4 1/2. I thought for sure it would be 1 1/2. I've killed a doe in the same area that was over 120lbs. Didn't age it though.
I age does by my game camera....had one with a broke leg that healed funny on camera with fawns every year since 2007
