For Araucanas, searching for "ear tuft" is much more useful than the breed name (especially because Araucanas in some countries do not have ear tufts).Okay, thanks for the links. I couldn't find anything for the seramas or araucanas especially (maybe i was searching the wrong keywords?)
For Seramas, searching "micro serama breeding" turns up some pages like this one:

(I still haven't seen anything about fantails, though.)
