I just wanted dark eggs, and wellies were cheaper and lay more than marans. I've read that if they are bred for it you can get them as dark as a marans, with spots. Hear it makes them lay fewer eggs though
Heck yeah they are super yellow yolks, almost orange, if you scamble them the scrambled egg is yellow, don't get that with store bought!
Eat the shells? I always wanted to when I was younger. Ever watch Hulk Hogan make his power shake back in the day? He threw a bunch of raw eggs shells and all, along with spinich and a whole bunch of other stuff in a blender and drank it raw, always wanted to try it when I was a kid so I could have big muscles like him Lol!
