Hank,

It appears that buck has a swayed back and pot belly.  This may be due to his posture in this picture.  His chest doesn’t sag much below where his shoulder meets his leg and his neck merges with his chest well above his brisket.  The buck appears very fit – no sagging anywhere It seems there are more indicators that this buck is three than four. Based on the quality of the habitat where this buck lives I estimate he’s three or four and I’m leaning toward three.  

Enjoy creation,
