Not sure. From what I've read on here I thought they could have either. What would you call him then? Father was an Ameraucana or EE probably and mother was either an EE or RIR. Its a possibility the father was a Buff and mother was an EE. He does show the ear muffs though. Has no spur developement at all though which is why I am wondering. I just assumed early on this one was a roo cause of coloration. Unfourtunately I sold the other 30 I had so I have none left from that hatch to compare to.
