There is a local person offering some coocoo maran hens. Do all marans lay the dark brown eggs reguardless of their feather color? We have some French Black Copper Marans in the bator right now but I'm new to marans. When I searched for images on Google I get what looks a lot like barred rocks - is this correct? Not sure since Google notes "related search: barred rock). Any one have a pic of a coocoo they can post? I've never purchased grown birds before - does $10 for a 6 mo. old hen sound fair? Thank you so much!
