I haven't popped it open to find out. Our table hens are slowing down. But, eventually, I will find out. This Spring or Summer as I am adding another set of hens soon, I plan on getting NPIP inspected and sell hatching Maran eggs. Until then, I plan on seeing if they taste any different or not as the lore goes. I suspect a chicken egg is a chicken egg, they just look cool.
They definitely look cool! Our hens have slowed waaaayyy down. 13 girls and we've gotten just one egg a day for the past few days. My DH put up a sign in the coop saying we need more eggs please. I asked why on earth? He said, 'well you talk to them I thought I'd write.' LOL
