Cows huddle together due to a sense of security

This is the most common reason to explain why cows often huddle together. Herd animals like cows, goats, and sheep feel safe in numbers! As cows can’t do much when it comes to an actual fight, being part of a herd makes them less vulnerable to be attacked by enemies.
