Not all my hens lay this dark. I have 3 bcms that lay real dark -all from different people. Cheepa who lays the darkest, I got from someone down near Tampa, bought eggs and hatched them. They were dark eggs. I believe they were wade jean x presley. The other dark laying hen I have is a bayhorse bonnie hen she lays a big dark egg (the one in the pic with the speckles that looks big) I wished they all laid that large. The 3rd dark laying hen I have, I got from pasofinofarms (hatched out from a dark egg). So I am going to try and make just a dark laying pen with the rooster who came from my avatar egg as the main roo. He isn't a perfect roo..has a high tail and a short back but should hopefully pass on that dark gene. I also have one blue hen, cocoa, from peachick who lays really dark large eggs. She lays darker than some of my other bcms.
