An Easter Egger is any chicken that possesses the “blue egg” gene, but doesn’t fully meet any breed description as defined in the American Poultry Association (APA) and/or the American Bantam Association (ABA) standards. To clarify, I was going on the fact that a green egg is tied to the blue egg gene since green is a color of egg not possible without the blue egg gene present. I just lump green eggs in with the blues. That being said: "Easter Eggers are everything from the reject Ameraucana to the extreme mutts." Yes, but only if they carry the blue egg gene and therefore lay blue eggs.
"Easter Eggers can lay green, pink, blue - if the blue gene has been outbred too many times, you will end up with cream, brownish, etc. eggs." No. Easter Eggers are Easter Eggers by virtue of the fact that they carry the blue egg gene and therefore lay blue eggs. An Easter Egger is not an Easter Egger if it lays anything other than blue/blue green/green. A bird that is the result of out breeding so that the blue egg gene has disappeared and therefore lays pink, cream, brownish eggs etc. is not an Easter Egger but a barnyard mix, a Heinz 57.
