I was looking at a different thread asking if their chicken is a cuckoo maran, and I notice the attribute of CM that most mention are the feet being black and grayest white. As for the BR as having yellow feet. When I saw a picture of one I notice that my BR looks alot like the CM. It doesnt matter what breed my chicken is but just curious. Would be exciting if it is a CM. So can someone explain what is the difference between the two, is it just the pattern of the barred? Or genetics ( ex. the type of gene) That's what I've been reading when I search google, still confused though. Any help would be great, thanks for everyone that replies
 
The cuckoo marans aren't barred - they are cuckoo. The lines are murky, less defined, much darker than barred birds.

Marans can be feather legged, and their shanks are pink/white. Barred rocks always have clean shanks, and they are yellow.
 
Hatchery rocks may not have the yellow skin; I have had several over the course of the years and none had yellow skin (and their eggs were not at all dark). Exhibition quality rocks will have very distinct barring, and exhibition quality marans will have very fuzzy barring. On hatchery birds, the distinction between barring and cuckoo can be pretty minimal. Genetically the difference is a slow feathering gene for barred birds and a fast feathering gene for cuckoo. (Same gene, different alleles.)

Rocks have a lot of personality and curiosity; marans (so I've been told) tend to be milder.

This isn't right, a cuckoo Maran is still barred.
