Other than it sounding as if he’s doing things in the wrong order, perfectly fine.
A good friend of mine is part of a strictly controlled and licensed wildlife management team on MoD land. He has a beat that he is responsible for, he has a certain number of a certain age and gender that he can take during the season. He grallochs them, takes them home and either sells on to a licensed game dealer (butcher) or hangs them in the meat locker in the corner of his garage. A week or so later he then skins and butchers the carcasses, turning that lovely meat into lovely food or freezer content.
If we butchered with the garage door open, his neighbours were a bit perturbed but there’s nothing wrong in it.
