|Not everything works out as planned|
Elk often run in herds and love to get into the hayfield, and no fence will keep them out. Their appearance and condition varies by the season. They change their coats with the season and sometimes have some other issues that affect their appearance.
It's quite normal for elk to travel in fairly large groups or herds. While the bulls may be alone or in small groups, the cows have a social hierarchy lead by a "lead cow" and large groups are common. They move around over a substantial area but often stay pretty close together.
