OP,
For hiring the goats, I'm curious, it sounds like the "goat service" (not sure what to call them) is responsible for the fence? Is it spelled out in the service agreement who is responsible for keeping them contained? What happens if they get out? Who pays damages for other's property, or pays for goats if they get hit on a road?
I'm assuming all the liability goes to the service provider?
I'd hate to get sued if goats (that I hired) got out while "fenced in" at my place, and caused damage or where hit by a car.
