I was out with the dog earlier today, near to farmland I shoot over, when the dog put up a Roe Doe from a thick patch of brambles, the Doe was moving slowly and looked confused, she ran/staggered about 60yds, crashed into some bushes and I had to physically push her back up onto her feet and set her going again. She had a bald patch on the back of the neck and looked underweight and generally unwell. I wasn't carrying a gun as I don't shoot over this land but I can shoot the farmland next door (boundary about 100yds away) I no longer carry a knife on me as I did as a boy, as it seems to be illegal nowadays.
The question is:
Can I shoot this obviously sick animal out of season? and if I do will I need to inform anyone? and what to do with the carcass?
Any other helpful advice is welcome
