Both are 7 weeks old. I thought both were roos but now I have my questions about the Birchen Maran. What do you think? The other chickens in the pics are Rhodebar and Bielelfelders. All from Greenfire. thanks!! Splash Barnevelder. I think this is a cockerel? huge feet, big bodied mild mannered I thought this Birchen was a roo, but it hasn't developed a comb yet. The wattles are starting to come in. He/she is very small and more timid compared to the rest of the cockerels. Sometimes has an upright stance, sometimes more low to the ground. Feather footed smaller feet. Is he a slow maturer and just looks feminine compared to the robust Bielefelder cockerels? thanks!
