Not unethical at all - in fact I when I grew up hunting - if a youngster shot a Button or even a female fawn, he/she got a pat on the back. Any deer is a trophy when you are first hunting.

As I grow older, I don't choose to shoot a fawn, but I'll be the first to pat a new hunter on the back if they take a young animal -

These leases that fine for taking fawns have no idea what they are doing. In most areas - the lease manager should require a doe be taken before a buck - ar at least before a second buck (if the population is high enough). If deer are really that scarce on the lease - then WAY too many members are hunting it.

Just my 2 cents.
