WARNING: When raising one of these prior to hatching be sure to have at least 3 fridges full of meat because these babies are absolutely savage and eat around three to five meat at a time! Help spread the word!
Argy, but with a twist. They deal “true” damage, albeit low, thus not hitting anything that is wild. Only carnivores agro to it. To tame, build a 3x2 cage, make it three frames high, put a gate frame with a gate(make sure to put it on auto close and open) on the 2-wide end of it and cover the whole thing with ceilings. Then pick up one of the frames. Kite it into the cage with a ptera and fly out of the opening you’ve made. Congrats, you’ve trapped yourself an owl. Use tranq darts - they are pretty fragile.
