PREPARATION: When the reindeer first arrive, they will tend to try to escape to "go home". So ideally, have a small pen with 6 to 7 foot high fence or walls to prevent this. Have grass, hay, water and feed dishes or trough there. They will call it home after a week or two and then they can go out into a bigger pen or field with 6 foot fences. Reindeer like to "play" in the fence with their antlers. The fence wire should be high tensile strength and stretched tightly or they will cut holes in it with their antlers. It should be predator proof. Neighbor dogs have been our biggest predator problem. We have used corral panels covered with plastic fencing (like snow fence) and that works well until they are rubbing the velvet off their antlers, and then they tear it up!!
