Don't know about Marans, but I have 2 Welsummers that are consistent layers of beautiful brown eggs. All of my hens lay brown eggs, but the Welsummers have a nice rich color...not what the copper maran can offer, so I hear, but captivating enough. They are curious, independent birds that will come up and see what you are doing if they get the chance. I can't say that this personality lends itself to being high in the heirarchical chain, but with free range it doesn't seem to matter. They are happy birds that forage with the best of them and are entertaining and social with people. We don't handle our birds much, though, and the Welsummers seem to prefer this, as they will fly backwards when they see a hand coming their way. Still, a bit of delectible treat will bring them forth with the best of them.
