I just ordered some Silver Cuckoo Maran chicks. I heard and read that they don't lay the chocolate eggs that I thought they would. I really wanted the kind that laid the darker color. I can change my order to Welsummers if I wanted to. I just want to know if they lay darker eggs then the Silver Cuckoo Marans. I guess a better way to put it is which lays the darker egg? Welsummer OR Silver Cuckoo Marans?
