So I realize there are different colors of the same bird for example the Orpington has blue, black, white and buff (plus splash which I realize is not a standard but comes from the same parent stock as Blue/Black). However there are other colors that are not recognized such as Lavender. Is this some sort of recessive trait or a mutation that is being bred for or is the blood of another type of chicken introduced to produce the color? That brings up another question: If you can not get a buff from a black for example then are they still the same breed? I realize they are all called Orpingtons but do they have the same origins? Or do they simply just have the same shape and feathering characteristics? I ask these questions because I have Buff Orpingtons and I like their temperament in particular when compared to my other breeds. I would love to replace some of my flock with more Orpingtons so long as they are going to be like my Buffs. Now I realize that each bird does have its own personality but overall I am happier with my Buffs than my RIR's or Australorps. I know my questions are rather pedestrian but I would love to learn more about this. I have been searching here and elsewhere on the net and either my ability to use google is not up to snuff or I simply don't know how to ask about what I am looking to learn. As an aside I would like to, maybe next season, invest in some heritage quality Orpingtons from a breeder but that is a topic for another time. Thank you in advance for any insight you may be able to offer.
