I'm going to throw my
in on this, FWIW, I don't think feather color has anything to do with a bird being aggressive or passive.
I've had birds that were hatched, brooded, and raised together eventually become aggressive toward their pen mates. I've also paired up dissimilar birds with no problems at all, and at other times it just didn't work. IMHO, it depends on the bird(s) natural aggressive or passive tendencies. Each bird has it's own personality, just like humans.
I have several male Reeves pheasants that are aggressive towards humans but not towards other birds, either of their own species or a different species. I have also learned, 'the hard way', that Reeves chicks will get along with other species for a little while, until about a month old but after that they will kill anyother species in the same pen or brooder.
The same is true of my Bob's. They get along fine with other species, until they start to feather out, then all heck breaks loose. So to make a long story short, I don't think feather color has anything to do with aggressive or passive behavior.
