Gents, does anyone have any solid evidence/literature on accurately calculating the age of our old mate Charlie in the FIELD?
I've shot quite a few and to be honest had a good guesstimate but being a little OCD I'm interested in being a little more scientific and accurate.
Ive done the Google thing and found loads if you can x-ray their teeth but nothing a bloke in a muddy field with a head torch can do!
This is purely me being a little odd but we've had a few Charlie's bagged around some of the permissions I shoot that I (and several farmers) think are Urban's that have been released by some 'kindly' organisation and I'd like to investigate a bit.
All the best!
