I know Ameraucanas have the blue egg gene. I'm just wondering what constitutes "blue." I have an older EE that lays a beautiful Tiffany blue egg. I have two younger EEs (about 8 months old) that just started laying. I think it's them. I'm getting some olive colored eggs that I never got before. I have a blue Ameraucana that just started laying, I think. I'm also getting a blue egg, but it's not the Tiffany blue like my EE. It has an olive tinge, but not enough to make it a green egg. It's just not bright light blue like the EE egg. I also have two EEs that are about 6 months old. I don't know if they're laying yet, but they could be. So, my question is, what makes an egg "blue?" The olive eggs are very Tiffany blue on the inside when the membrane is removed. Is it most likely that the Ameraucana is laying the new darker blue egg? Do they lay a range of blue? The front center egg is the Tiffany blue EE egg (she's been laying that color for over a year). The lighter on the left could either be considered pale olive or dark bluish-green and are the ones in question. The five on the right are olive. Two are speckled with red and three are not. I got one yesterday that had so many speckles it looked brown until you looked closely. The inside was bright blue.
