What breed is the best layer of dark brown eggs?

[feedstorechick]

Are any of the dark brown egg layers as prolific in the number of eggs they lay as the other laying breeds?

I have a Welsummer hen and a flock of Marans; both lay a nice, dark egg, though the Marans is much darker. Both are good layers, but they're not a "production" breed, so they're not prolific layers.

I would help to know what you consider a "dark" brown egg. The real dark eggs are from Marans, Welsummer and Penedescencas. You probably can't expect much more than 180-200/yr out of any of those. If you would consider something lighter, then your choices widen quite a bit and the lay rate goes up quite a bit on some.
