2 in the trunk, 2 in the back seat, 1 in the rear passenger side footwell, 1 in the front passenger side footwell, 1 in the passenger seat. That’s seven. How you get them to stay in those places, how you avoid them ripping the interior to shreds with flailing little hooves, how you get the shit out of the upholstery afterwards, none of those are my problem. 
And I assume none of the calves were wearing seatbelts? :mad:
I once transported 3 young pygmy goats in my acura integra (hatchback) as a favor to a friend. It was very easy. However, goats usually do not urinate/defecate during a short trip. Calves, on the other hand, go at will and typically have very loose feces.
