They are definately true rumpless Araucana. I got them from a reputable source, anyway. I saw pictures of the pens, of course assuming it was true, but I am pretty confident. They are definately rumpless. Now that everyone is totally fluffed up I really can't tell if it is tufted. It's neck looks slightly different than the chipmunk one, but not significantly so. A black one with some black on the legs (but pink feet area), white wing tips and white belly hatched last night. It's neck has the same different appearance as the buff one. It is a very subtle difference from the chipmunk one so I may be seeing things! And erinszoo thanks for posting those pics - super helpful!
