Visitors don't go unnoticed on the farm. Some, I might add are not welcome either.
Interestingly enough one dairy farm is going to have several visitors. Scientists from the University of Exeter plan to visit a farm in Devon to study social interactions in dairy cows; cow friendships, if you will. They will be wearing proximity collars that will record/transmit data on their habits. In other words, they are going to use fancy equipment to find out who your BFF is. Couldn't they just ask? I know who my trusted friends are and I know which cows on the farm have such bad breath that I avoid them at any cost! Perhaps a study on cow toothbrushes and mouth washes could follow this one to see if friendly relationships improved.
If you'll excuse me I'm going to make sure Duck, who is definitely not my BFF, has really left the premises.
