Andrew Castle is Leading Britain's Conversation.
Why don't you ever see sheep and cows in the same field?
Name: Robert, Surry
Qualification: Spent five years milking cows twice a day.
Answer: Cows and sheep have different malfunctions for eating grass. Sheep chew grass low to the ground. Cows use their tongues to pull grass up. The sheep cope with short grass but the cows need long grass. Sheep can go in the field after cows.
