Without going into a lot of detail, your birds are Ameraucanas. If they breed predictably true for a recognized color and have all the right characteristics, they are Ameraucana, whether the APA recognizes them in that color yet or not. Yes, splash to splash yields all splash offspring - they breed predictably true for color. There are a lot of self-proclaimed experts on the internet, but if you want good information go to the Ameraucana website. I know this will be censored and probably deleted, but I'm telling it like it is. Also, I checked out your source's website. Do not believe everything they are telling you there, because it is not all true.
