How many generation would it take to breed out rumplesness from Araucana?

[nicalandia]

I would have accepted this but I had a rumpless bird show up when I started making crosses with blue egg laying Brown Leghorns. Neither Silver Laced Wyandottes nor the Brown Leghorns exhibited rumpless. Yet one single hen laying white eggs was rumpless.

There is also a recessive Rumpless

the American standard are rumpless. Elsewhere, here for example, standard Araucanas do have tails (and no ear tufts)

Okay, but presumably if they had those, they wouldn't be wanting to breed either out

Elsewhere, that is true but elsewhere is a broad generalization. In Britain and Australia, yes, but in Europe there are Araucanas just like ours but many have beards. And that is only Europe and Australia. I don’t know what other continents are like.
