Logged on and saw my tames were killed by a kairuku..How?!?!

Pelagornis will gather much more from babies than adult kairuku

So I had a hard time getting organic polymer, one day I just happen to see these things and go” aaawww, your cut, now I want to kill you”. After that I got so much polymer after killing an entire Colony of them

Kairuku are found in the coldest parts of the map, you'll want fur clothing to keep you from freezing to death.
