I always find them near start of the ice biome on the cliff face on the western coast, past the Red Beacon. Make in angry, lure it off the cliff and then shoot from on the cliff. It doesn't have anything but the occasional alpha although I've only seen 1.
If you find this thing RUN it took me out in two hits and completely demolished my home and murdered my raptor and my little otter cuddles please like to pay respects to my little cuddles kept me warm on the cold nights
You might think you got it cause your started breeding when the server sun rose on day 1, but I'm here to tell you... run, cause it won't. If you agro this tickle chicken of the forest, he will tickle your guts out weather you concent or not. If your tame is shorter then he is, I suggest running. He will slap you off your tame and leave both of your corpses on the jungle floor.
Yesterday I was playing and it appeared by my house when I woke up after it killed all my dilos and a para and destroyed my chest that had 1,012 hide if one is close to house put all your stuff in a chest and get its attention then run as far away as you can lead it away from your pets
