I rescued 3 hens a few months ago, two I assumed were barred rocks one Columbian wynnadotte. Well I have several barred rock hens and roosters. After reading a article on cuckoo marans I looked at the picture and they looked exactly like my two "barred rock" hens. I took a closer look and found my other BRs had yellow feet and the two in question had white feet white skin. My question is the marans are supposed to be chocolate eggers and my two lay large normal colored brown eggs. Any idea if they are marans or just barred rocks? Any other tell tale features?
