I’m not sure what breed it resembles but she is GORGEOUS!! I thought “lilac Ameraucana” when I first saw the picture. Whatever you did, please share! I would love to get a flock of these!
Easter Egger. Tractor Supply doesn't sell ameraucana, although they're often marked as 'AmerIcana'. Note the spelling. If they're spelled that way, then they're Easter Eggers.
