Golden Comets and Amberlinks are Sex-Links, crosses, so unless it's just a 4H showmanship kind of thing, they cannot be shown. There's no standard or purpose in showing crosses.
Your Araucana is more than likely an Easter Egger, a mutt, as hatcheries/feedstores/most local people claim to have such but they're actually colored egg laying mutts called Easter Eggers. If you enter in a legit show as an Araucana they will disqualify you so again, if it is a 4H type thing I can't help you but you could probably do it, if it is an APA type show, I'd recommend you not enter it.
