Its not the rumpless gene that is bad when bred together, its the tufted gene. Those birds definetly have a lot Araucana in them. My guess is Araucana/ Ameraucana or EE, or Araucana bred to the European standard and not ours. Not all Araucanas have tufts so the lack of tufts on these doesnt mean they arent Araucanas. The muffs and beards indicate either a mix with EE's or Ameraucanas or European standard Araucanas.
