RE: life span of a deer
I have heard of does that were in the teens and even read a couple of stories about 20 year old does...I can't recall if they were wild though. I would guess 7-10 years, but so many things factor into the mix I would think pretty hard to get an accurate or ave. life span. I have shot deer that were 10 or approaching it. Last fall my buck was aged at 10 and this years buck was rough aged between 7-9.
Good thing new ones are born every year!!!
