I see lots of threads referencing ages of deer. Many reference deer 5.5, 6.5 and even older. I dont think its an intentional embellishment but its incredibly rare for a buck to reach those kind of ages. Even in a situation that im in where there are pretty big tracts of protected land and hunter restraint ( i havent killed a buck here since 2016) , and i overlook these deer 365 days a year- it pretty darn hard to get one past 5.5 before they fall of the grid. So my question is, what criteria do you use to project a deer is say 7.5 yrs of age.
