I have what I thought was a Maran (cuckoo) that just laid a green egg! She is is with just 7 other chickens. Four lavender Orpington, one rescue sex link (at least 6 yrs old) another austrolorp rescue ( at least 6 years old) and her. I can’t understand why it’s green. She is just 4 months old..born March 4th. Any ideas? To look at her, she’s a Marian, but I’m thrown for a loop now. I’d love to hear what people think. Her sisters are also laying green eggs.
