So here goes. When I picked out the breeds I wanted, it was based pretty much solely on temperament. So I chose barred rock, cochin and light brahma. When I got my first 4( 2-pbr, 2-cochin) all was well in the coop and very little angst. Yesterday we got 2 lt. Brahma girls and hey things are in an uproar. The 2 BPR's that were the clear leaders are now consistently running away from the brahmas. One of the Cochins also scurries away, but one does not. It seems like the brahmas are only interested in messing with my dark colored birds. The white cochin seems fine. What are your experiences with interaction between different breeds. Oh and none of these shenanigans has been overly aggressive, just a lot of clucking and chasing.
