How are horses behavior when they are grazing?

Answer 1

The behavior a horse displays when grazing will vary slightly according to whether it is alone or in a herd. When alone a horse will be more watchful, often taking a bite and lifting it's head to chew and watch for predators, possibly spooking at 'nothing' more often and moving on to new areas more quickly. When in a group one horse will keep full watch while the others graze and periodically check for danger, they will be a bit less spooky and stay in one place for a longer period of time than a horse that is alone.
