Until today I thought Marans laid the darkest eggs and have admired the pics of the chocolate brown eggs. But today I've seen two posts indicating that Welsummers also lay dark eggs. So now, because I'm curious and always willing to learn something new, I'm wondering which are the darkest overall? I'm sure there are exceptions to every rule (for example, some Marans lay exceptionally pale eggs while some Welsummers may lay exceptionally dark eggs) but as a general rule, which breed would be considered to lay the darkest eggs?
