Hey Everyone, I wanted to share some pics of one of my Pure Blue Orpingtons, He comes from a line of Blues that were breed on blues for a couple generations...as I was informed......I acquired a large flock with two roos and 10 hens a year or more back.. When I first got him I noticed one brown hackle feather. His brother is long gone now but didn't show any signs of this. This particular rooster has an issue with one of his legs, an injury healed wrong from when he was a youngster... He can get around by hopping, he eats and drinks fine and no one picks on him. He can't breed what so ever, and seeing how he still has a great quality of life we keep him around. I want to use him to fertilize some of my hens, to keep this line going, and to mix into my Black Orp line, I will most likely have to AI his packet into a hen. But before I start and use this fellow for breeding... I am rather curious about this Brown/Chocolate colouring he has feathered out. Over the summer last year and into this winter I have noticed that this one brownish feather, is not so alone any more. He now has many, a few of the hens that come from this line don't show the same colourings, and so far I have not seen any in the offspring. I just sold all my Blue cockerels a while back, Haven't heard or seen any that have this same colour difference. By no means am I an expert so I must ask here... what would cause this coloration in his hackle and back feather?
