The 4 girls I got last month are supposed to be americauna/ EE. They gave my cousin blue green eggs. When I started getting an egg a day about a week ago I assumed it was from my golden wyandotte Olive. Today I'm cleaning the coop, the americaunas are showing a lot of interest in the nests so I shut the door and let them be. I come back in later to find the same kind of light brown egg that I have been finding and in the same place I've been finding them. There were only americauna in the coop. What gives?
