Don't know what you are doing wrong.

after taming they become hostile with native life and anything at all will set them off (destroy their pen) or the enemy (not counting deer) will attack the pen to get at them. You probably have your spawns under control.

Ive gone the other direction... my guy is just the 1, he is for riding and I hunt wild to eat. My tame is free-range (no pen at all) one smashes every pig, deer, or greyling that dares to set foot in my area, providing a good deal of free rocks, wood, meats, and resin etc every day. He has almost completely cleared a whole section of wood and rock near my home.

They are less destructive if you are not at home. But if you hang out at your base for hours, it can be rowdy.
