I'm sorry to be entering this thread in the middle of a conversation, but I have a question. I hatched my first group of Marans about 4 weeks ago, and ended up with 3 Black coppers (2 pullets, 1 roo) and 3 blue coppers out of 8 eggs (2 pullets and 1 roo).. I know.. crazy good luck! 2 of the blacks are feather shanked, the blues are clean. But this is where it gets weird: the blue copper cockerel has NO TAIL. He looks ridiculous! Everyone else has nice fluffy tails coming in, this guy doesn't even have a wisp of feathers starting. I'm baffled... these are Krebs line marans. Has anyone ever heard of this happening? Maybe the Araucana roo got into the marans pen?
