Ok, I know that the European type araucana is different than the US araucana, I don't know if the European type ameraucana is different then the US type. Let me know if it is please. But I would guess you could breed them and once the chicks are mature take the smallest combed ones and breed them back to a english type ameraucana. Keep this up and it should shrink the comb size down, but I don't know how long you would have to do this back breeding. I would go the easy route and just get some more lavender english type ameraucanas
Thanks a lot. It' s very kind of you to help me. Here is a photo from my English type lavender araucana... I know the easy route too but I'm from Greece and it's very difficult to find true to type ameraucana here...
Those actually look like the European type of araucanas, since they have a small crest. If you can, see if you can find a solid black ee to use, than you might not end up with any other colors but black splits. After enough breeding back to the lavenders (whether to your hens or your rooster) you will end up with lavenders.
