If a tailed Araucana and a rumpless Araucana have chicks, what percentage will be rumpless? I have 2 Araucana mix chicks that are about 4 months old. I know the hen was my tailed Araucana Peanut. But there were several different breeds in with her and I'm trying to find out who the daddy was. The chicks, a pair, are solid black, cockeral has some mahogany saddle and hackles coming in. Both have pea combs. Both have very dark, almost black skin on their faces. Legs are black. The roosters in with her at the time were my rumpless Araucana Franklin, black with gold leakage, a frizzle black naked neck silkie cross, a mahogany naked neck, a silver silkie serama, and a multi colored little game rooster. I never saw the naked neck try, or the serama. The frizzled tried but didnt seem to get anywhere. But the game roo and Franklin always were. But color wise, they look nothing like the game. They have fully feathered necks also. Could the rumpless Araucana not produced any rumpless chicks? Can anyone take a stab at which roo this was?
