Hi comb is rather large but if you can get ahold of a hen with a really small tight comb and then selectively keep the pullets with small tight comb you shouldn't have any trouble getting rid of that in your flock. I found it fairly easy. His wattles are on the large side also, but again as with everything about Araucanca your not going to find the perfect bird, you have to breed for it. Each persons idea of perfection is different.
His color is beautiful, and since nothing about his color is an accepted color, I say go for it. Feel free to breed him to what ever you have and see what you get. If you are wanting to go for the standard of perfection in the APA it would be best to start off with a different bird since his color is way off. But for me personally color isn't as important as body type, leg color, egg color ( even though I have two green egg layers, my bad), tufts, rumpless, comb and so on. Those items alone can keep you struggling along for years. LOL!
I believe Ann Cushing of Willow Hill Araucanas has the best body type I have ever seen on Araucanas. Gary Rameys birds are really lovely, I have a few, mine are on the smaller side but their shape is so nice. Ann Horsman has good size birds with good bodies also. I had 1 roo out of Ann Charles ( gotta love all the Araucana Anns as I call them) who had the most amazing tufts, really very perfect. Then you have Hinckjcs beautiful soft colored lavendars, amazing. Each breeders birds look just a little different to me than the others. They each have their idea of what the perfect araucana should look like.
