My 2 Ameraucanas. You can see a clear difference in size.
3 days old he also makes a different sound than my other ameraucana.
And here is all of my chicks. You cant miss the little black one. Hes so tiny if I didnt know what egg he came out of I would think he was a serama. Not sure if her male Serama could impregnant an Amerauana and still get a blue eggs??!!
I hate to say it, but those don't look like Ameraucana. Those look like Easter Egger chicks.
Hope that little one makes it.
