While I am waiting for a French Wheaten Marans Roo to mature, I have left a Lavender Araucana Rooster in with my French Wheaten Marans hens. As some of my other hens have gone broody I have given them some of the Marans eggs to hatch. The first lot of chicks all look the same except one. 5 are dark brown, like a young Marans roo, and 1 is a light brown/grey colour. All have the Araucana type comb, and most if not all have feathered legs. I'm just wondering if the difference in feather colour on these chicks could be an indication of their sex? I would be interested to hear anyone's opinion and maybe guess as to which colour belongs to which sex. Any help would be greatly appreciated
