I am pretty sure this chick is a cross between a black copper marans and a lavender ameraucana, but not 50/50. It hatched from an olive egg, and I think I was told the dad was most likely a lavender ameraucana.
It hatched around 10 weeks ago.
I lean towards it being a pullet- there was a total of 6 chicks hatched, and two of the boys (pure lav am and a pure bcm) are both really obviously boys. This one and a lav am are the only two I have doubts on.
