I dont shoot adult hinds at this time of year simply because I dont want to leave a fawn to die slowly over days. That is my ethic. It is not illegal to shoot a hind with a dependent and I admit I have done it once by mistake when I was 19.
For anyone who shares the same ethic but is not sure how to judge if the deer is an adult or yearling there are points I look at. A yearling is much narrower across the back, pins ( hips ) and is shallower in proportion to her length than an adult. She will have a finer head but so will a two year old hind that has her first fawn. The udder is a certain giveaway
I went for a drive to the hills tonight and in fading light it took 20 minutes glassing from 400 mtrs starting at 9pm to establish that one animal was a yearling hind and the other a 2nd calver (fawner) from last year.
