My dad wanted me to help out on his farm every once in a while, and one of my jobs is to get the 2 pot belly pigs into out trailer. How on earth do I get these fat pigs into the trailer?
Don't forget that pigs are roughly as intelligent as dogs and as stubborn as mules. Coercing them is easier than forcing them.
You should call them to you, lure them with food like cheese and block their way backwards in case they change their mind.
What you should avoid is pushing them from behind, pulling them by the ears and causing them pain or panic.
