We have our own way of moving cows in the South. First you blow the horn on the old jeep, then yell, "Come on girls! Come onnnn" and they will follow you anywhere. Call your lead cow by name and she will call the others . "Alright Tess, bring em on".
Plan ahead! Be smart and grow your own forage made with a hydroponics system to avoid facing acute shortage of feed and fodder resources.
