Our beautiful Butterscotch from Meyers Hatchery also lays the palest minty colored eggs. Sometimes they're more blue than green, other days the opposite. Once the egg was so pale it was almost white. She was also a late-bloomer, starting at close to 7 months old. However, she lays 6 eggs a week regularly. She's also my only lap chicken, often pressing up against my legs like a cat and looking up at me with that pretty fluffy face until I pick her up and lay her across my lap, where she dozes and melts into a fat chicken puddle on my legs. We just love her!
