I think Tribe 1 here has the easiest to identify structure. I think some of this has come about because they are family.
Tribe 2 is pretty fluid though. Punch is so relaxed about everything that he's virtually horizontal and Mag is just a really nice chap at heart it seems. Bracket thinks she's in charge and the rest just put up with the noise. Nolia is the most senior hen and from time to time lets everyone know it.
Tribe 3 is just odd. Myth is the most senior and Notch's favorite. However, Knock can't stand Myth and goes for her frequently. This involves lots of noise and Notch making conciliatory noises. Donk is a bit stranger than usual at the moment. Enough so to leave me a little concerned that she may have health problems, possibly worms.

I'm going to worm her just in case.
