I and a friend have had 10 from MCM over the last two years, I gave mine away since I was not that happy with the way they laid. I am not sure how to rate an egg on the the 1-10 darkness scale. The eggs were slightly darker than the Red Sex links / Red Stars I have that are the same age. They CM eggs were a little darker at the beginning of their laying cycle, then were about the same color 3-4 months later. The CM eggs were slightly more "brown" brown than the Star eggs which are more "red" brown. About half the CMs laid speckled eggs with darker brown spots, especially at the beginning. Even when young they do not lay very well in my experience, maybe 2-3 eggs a week if I was lucky, they fewer eggs they laid the darker they were. The Stars lay twice as many eggs and the eggs are much larger. The CM hens themselves were good size (weighed them to worm and they all were around 6-7 pounds), their temperament was very nice, calm and quite friendly to people, they were no problem with the other chickens. They varied a fair bit in feather color also, some had almost as distinct barring as barred rocks and some had very black barring. As chicks they were also very slow to feather in.
