I believe (on not a lot of first hand evidence but lots of anecdotal evidence from experienced keepers here where I live) that these types of problems occur more often in mixed breed flocks. Many people report that if they have pairs of triples of a particular breed in a large mixed flock the breeds bond by breed.
Here it should work even better and generally does. Not only do they have breed genetics, they also have family genes.
The most problematical with regard to in tribe disputes and bickering are the Marans/bantam crosses. Gedit and Myth, completely different sizes and generations will stick together. They are very similar in physiology apart from a very pronounced size difference.
It's not a very popular line of research. Any conclusions would be open to misinterpretation by various groups, much like Darwin's Survival of the Fittest.
