This wasn't today, but yesterday. I was leveling up some Yutyrannuses with my friends (one of which was in the redwood forest) and I came back to my base to make sure nothing got hurt while I was gone, and I notice a light blue unclaimed dodo waddling around. I got really confused, since I play on a non-dedicated server with three friends and no other people, and I claimed it, and went into my breeding building where I had been breeding dodos in a pen for the past few days. Inside, there were probably 50 unclaimed dodos wandering around inside of the building. I'd say 20 or so were in a 1x1 foundation where I had dodos breed. I tried to smack one with a sword, and then all of the unclaimed dodos went insane and started killing all of my beautiful mutated dodos. Three dodos got killed, (I was particularly sad about one of them because she was the re-incarnation of a baby dodo I hatched previously then it died instantly) and by that point I had either slit the dodos' throats or bit them to death with my Yutyrannus.
A while after that, I brought roughly half our mutated dodos to our taming pen and started sacrificing them to a Troodon. During the hour it took for the troodon to kill most of the dodos, I started breeding my four microraptors so I could have an army of them and destroy everything. (They took a Theri down in less than 5 seconds) After I fulfilled my murder quota, I headed back to base and went to check on my dodos and found a dodo with 77 mutations!
