If you cross them with New Hampshires and don't breed too tufted birds together you shouldn't have any issues. Or just buy an Araucana with no tufts in the first place.
Yes. If you breed two tufted Araucanas together 25 percent of the offspring have no tufts, which is typically not what the breeder wants, so if you ask I'm sure the breeder would be happy to get rid of some of the non-tufted ones.
