🎯 Field Aging Quick Tips
Look at the belly line first
A sagging belly that drops below the knee-line is one of the most reliable mature buck indicators.
Check neck thickness
During the rut, a mature buck's neck will appear nearly as wide as its shoulders — a young buck's neck looks thin.
Face profile matters
A Roman nose / drooping muzzle is a telltale sign of a 5.5+ year old deer — young bucks have a flat, "doe-like" profile.
Tarsal glands don't lie
Very dark, heavily stained black tarsal glands are a strong sign of a dominant, older buck during the rut.
