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.
I use a cross bow its almost 50/50 chance it will kill it but if that happens you can just pick out a different kairuku, and feed it raw fish and/or raw meat to tame they are very easy to tame almost dodo like in a way
