ok I know this question has been asked a zillion times on here and I have looked at other post and still cant understand....what is the difference in americana's araucana's EE?.....are the americanas pure breed or the araucana's.....I have ordered 50 araucana's from a hatchery...what will i expect to get?....I have 25 chicks now and they are striped on the head and already have earmuffs....some look blueish in their wings....thanks for all input
