I just noticed one of my 1 week old chicks has green legs. It’s a barnyard mix chick. Papa is a mix of Red Orpington roo over one of my blue hens who I believe to be a Rhode Island Blue. Mama is (pretty sure) my other blue hen who I believe to be a Blue Rock. I don’t truly know which hen is which breed. My other laying hens include specked Sussex, silver laced, gold laced, and blue laced red Wyandottes, and lavender Orpington. It’s not impossible I have the mama’s breed wrong. None of my chickens have green legs. I’ve heard it’s a EE trait but I only have brown layers. Any idea what these green legs mean or where they could come from?
