These guys all look to be 2 1/2 or 3 1/2 to me but aging on the hoof is tough in person and even tougher from photos.

Just read an article from 2010 that said a study of professional deer biologists judged the ages from a group known-age deer. The pro's were right less than half the time when the deer was older than 1 1/2 or younger than 7 1/2

Looks like you're in for a good season though!
