I just went out to the coop and I found these: One is green/olive and the other is blue except for where some water dripped on it, it is green/olive also. Why is it blue??? And who laid it?? We have never gotten one that looks like this, so I am stumped. We only have 4 pullets and they are nearly 30 weeks old. They all have Araucana in them, but not sure what the other breed(s) are.
