You have gotten some good advice. I've lived in Wy for 25 years and killed at least 1 every year except one. They make great sausage and jerky. Getting them cool fast is very important. The cleaner they are the better they taste. A couple of years ago I watched a couple of guys do the final cleanup on a goat they had killed that day. It was hung in the landowners barn. The hide was off. They were wiping out the inside of the body cavity with a mixture of vinegar and water. It was CLEAN when they got done. Then they put him a game bag. We have sometimes cut and wraped our goats the same day. We're very careful about hair and fat.
When I first came to WY a friend took me out to kill a couple of does. He always claimed that he liked to eat them better than deer. My son still feels the same way.
Most antelope hunts
occur at the end of the rut. The bucks can be a bit smelly. 20 years ago I got on a private ranch to hunt. I saw 34 bucks before I shot one. He was just standing around feeding. When I walked up to him I could smell him from 15 feet away. I cleaned him and washed him out and got him home. Still smelled in the garage. Got the hide off and the smell dropped by 80%. CAREFULLY cut and wrapped and he wasn't too bad. Last year I saw a couple bucks so worn out by Oct. 7 that all they wanted to do was eat and sleep. Saw the same buck in the same bed 4 times over a 6 hour period. I think he was too tired from the rut to want to do much.
I like to wash my goats out as quickly as I can. I'll carry water for that purpose if the area I'm hunting doesn't have running water to do it with. Good luck. Bruce
