Pick up a beautiful unicorn with an Argy , eagle. Drop in taming pen or in a very safe base. Here’s the thing; I only tamed an equus but what’s the difference? Don’t just tame out of the blue. The always run into terror birds or Carnos or raptors or all together.
If it won’t allow you to feed it, knock it out and let it wake up then try again. Most likely due to the fact someone else tried to tame it before. Also, it tells you when to feed it at the bottom corner of your screen. PLEASE UP THIS
