Chaotic will be passively participating in the rut.
That is, he will not be doing so officially - he will not be actively looking for a fight or for does - however he will not be offended if someone shakes their antlers at him, nor will he back down from a fight or be interfering in the battles of others for the season.
Unless, of course, they are undead/zombie. Then he'll hate their guts and want to kill them anyway.
Ta~!
