The wiki says that you cannot tame them unless they are adults. Well I call B.S. because I tamed a baby Kairuku/Penguin by just shooting it with Tranquilizer arrows until it fell asleep and offered it meat. Don’t trust what the people on the wiki say unless it’s from a trusted source.
They are so cute! I tamed one today and I named it Karri. She is a juvenile and very weak but still cute. If you kill baby or juvenile kairukus on purpose. I will find and burn your base in multiplayer.
DO NOT MAKE THE SAME MISTAKE AS I DID. I hit headshots when trying to knock this oversized penguin out, and it died... Just remember to go for the body, and only use tranq DARTs, otherwise it will die, please share to others
