Are these some of the same genetic make up of the Araucana, Ameraucana, and the Easter Egger? Here's what I've found on them: From Sand Hill Preservations Catalog. Manx Rumpies: Rumpless, variable color and comb. A very rare breed that lays colorfuls eggs and are difficult to breed. They have various comb types but small single combs are the most common. The abscence of the tail makes it a challenge to get fertile eggs. They are superb layers, but fertility rate can very low at times. This breed is not yet listed in the APA Standard. Chicks $6.00 each (5). Resolution: Are these some of the same stock? Wouldthey be good to use and try to breed?
