I have 6 hens, one of which is around 4 years old named Lacy. She's a silver laced wyandotte with a calm nature. All winter she has had the rattiest looking feathers, thin, ripped, broken, you name it. My Mom says she looks like a frizzle. Her comb is bright red and healthy and acts as she normally does. For awhile i thought it was a bad molt but she doesnt lose the feathers they just get torn. I checked her for mites and i dont see any in her feathers and she has no bald spots but today i saw black around her eyes and on her vent, but not bad and they didnt really look like mites to me? I have no idea, for the first time since having chickens i am clueless. Should i be worried and when will those ugly feathers fall out?! Its been MONTHS. Also none of my other hens have this issue, they are beautiful. Lacy also isn't laying, but it is winter so i didnt think that made a difference.
