The hide on/hide off thing for us relies on the temperature, now we don't get to hunt until after Thanksgiving, so often we can leave the meat hang for a long time. If it turns warm, however, we will get the hide off quick, quarter the moose and get it out to the butcher fast.
This year we get to calf hunt.. if you've never done that, it's a controversial moose management technique used in Ontario. Shooting a calf isn't hard, if you can get it away from momma moose, but you may have to deal with pissed off momma afterwards. So far it's only happened to me once. If I had been alone, it would have been a very dangerous situation. She was a bit leery of charging the two of us together. But when we separated, she would charge. Gun shots, useless, yelling useless. I chased her away with a big bell that one of the deer camp guys had made as a prank to get the others out of bed.
Calves I have shot since have been without issue, although one I shot at the end of legal light, I found momma standing watching me when I stood up from gutting. She ran when I raised my arms and yelled like a mad man. Good thing, i was alone, I had no light, and no big trees to run behind, just slash.
