In a former life, I worked for a package delivery company. It covered a large area, and a lot of it was very rural. That's my main experience being on farms, as I went to many, many, many Wisconsin farms throughout my time working for that company.
The roosters I was thinking of were actually just on someone's "regular" property. They would come out and I'd actually just sort of have to gently drop the box by the garage door and not really get out of the truck. Very protective birds. :)
