The other really big difference is the Roosters. It is a very different flock dynamic when you have one rooster, even more so with multiples. For the most part the Boys here all roost together in the same coop, and the Mature roosters and hens raise the young cockerels. It changes their behaviour. I think because @Shadrach had the separate Roosting setups with one Rooster each his “tribe” separation was even more apparent than mine. It’s why I still use the term flock in referring to my overall free range group. I have the one big flock with multiple Roosters and separate core tribes, and some hens that move between those tribes, or are completely outside them. I still get the “racist chickens” issues where there is often more cohesion between physically similar groups, and groups that arrived/hatched out together.I don't think my tribe is as stable as Shad's was. It tends to be very fluid & I have more ornamentals. Feathered feet, frizzling & the tiny Japs mean very different dynamics to the birds like Campines & Vorwerks.
