Easy tame, just use bolas, trap/protect it with spike walls, feed berries, and use narcotics/narco berries to keep torpor up. I play on a small tribes server and tamed a max level in less than an hour with 3x.
Deers are easy to tame because all you need is to find a good level deer and bola it and punch it out or tranq it or club it. And feed it meoberries. Also narcotics or narcoberries to help to stop it from waking up.
