I have (5) BA's that are all 12 weeks. Since they have been fully feathered, (2) of them are feathered differently. Each of the feathers on these 2 are all frayed out, and look like they have had a perm. (almost like they have curly hair) They have all the features of a pure BA, including the green tint in the sunlight. My other 3 BA's have nice smooth coats, and the outer edge of each feather is actually a darker black outline. They are not molting because they have been this way the entire time. I bought them from a local feed store so it's not a guarantee that they all came from the same hatch. Could this be something that was bred into them, either from mom or dad? They are also the only 2 of the 5 that do not have distinct combs yet. They have no pinkish or redish colors on their faces as the other 3 do. I know they all mature differently, but I'm just now starting to think this is kinda weird!!
