One of my 6 chicks is a cookoo marran. I cannot remember which one the guy told me is it? Do they have big fluffy cheeks? I will try and take individual pictures this evening after my kids go to bed. I have 2 New Hampshire Reds (straight run), 1 black wyndotte, 1 splash wyndotte, 1 easter egger, and 1 cookoo marran. Here are the pictures I have. I think they are only 1-2 weeks old.
