Oof. To my nose among the most offensive odors was dead poultry. I own the farm I grew up on now. Don't do livestock anymore and don't miss any of that either.I love the guys who complain about the smell of Ballistol, the only thing I can think is that they are city boys.
Go live on a farm for a summer and clean out stalls, chicken coops and find the dead animals that have wandered off and died in the woods and have been there for a few weeks in summer.........Oh, and the outhouse that we all had back in the day.
City boys do not know what stink is.
