Lol yes, they are most definitely "breedist" if you have enough of each different breed... I hadn't been able to come up with a goodcterm for that, as "racist" and "sexist" don't quite cover it
I have 6 BRs, 5 of which are ALWAYS together, even next to each other on the roost; 8 SSH, they are always together, and the roo in that bunch prefers his ladies of the same breed before anyone else; 4 EE, they tend to wander by themselves but roost together; 4 Wyandotte that are a mini flock of meanies lol; 3 silkies can be found in a pack, but the roo prefers the Wyandottes lol; 4 BAs that stay together and tend to follow ME rather than other chickens; 5 Ancona who take the 2 Buttercups as part of the crew, they all are too good for the coop and sleep in the trees
Then I have a banty Cochin, a standard Cochin, a Red Star, and a lone cockerel chick from the banty that are loners, really they don't follow anyone but themselves, and a Blue Andalusian roo to watch over them all
They will form gangs within broods, as well. So chicks hatched or shipped together, raised together, will always have a better bond than ones integrated in. I like to keep them going in by at least pairs, that way they don't get isolated and picked on.
They roost in 4 different houses/areas, forage in different directions, and have obvious pecking order arrangements as far as roosts, but come feeding time, they all eat together just fine
PS, out of all those breeds, if you want docile good layers, the Australorps, Red Star, and EEs have great personalities, the BRs, not so much on the nice personality lol, but great layers.... For broodies and lap chickens lol, go with silkies or Cochins
