I can see the americauna, but the images I found of Americauna roos have darker feathers not white. Is that standard? I am pretty sure Mutt is a hen since we are getting a white-ish egg. I assumed that it was Mutt but maybe I'm wrong since all the other eggs are brown and the same size. Thanks for the ideas.
Mutt isn't an Ameraucana...Ameraucana's aren't mutts. EEs are mutts so therefore...he is an Easter Egger. When I was sold my 6 chicks I thought they were Ameraucanas also because that is what the feed store sold them as.
The Ameraucana Breeders Club defines an Easter Egg chicken or Easter Egger as any chicken that possesses the blue egg gene, but doesnt fully meet any breed descriptions as defined in the APA and/or ABA standards. Further, even if a bird meets an Ameraucana standard breed description, but doesnt meet a variety description or breed true at least 50% of the time it is considered an Easter Egg chicken.
Hope that helps clarify a bit.
Yours is definitely a roo since you can see the pointy hackle and saddle feathers quite clearly.
