This is not a typical butt feather problem, nor is it necessarily a problem at all, but one of my Wyandottes has started growing very long, wispy feathers on her fluff butt and thighs. Some of them resemble down feathers, while some have a visible shaft, except it's very thin and elongated compared to the normal, more compact feathers. I even noticed one forming up on her shoulder/neck area. They look like they've come loose and just hanging there as they are a few inches beyond the rest of the feathers. I noticed a couple a few months ago, but now there are a lot of them! Anyone ever seen such a weird thing? I tried googling it, but wasn't able to come up with anything that looks or sounds even close to this. It makes me wonder if there is an underlying medical issue or deficiency that is causing the new feathers to be deformed. If it's something treatable or contagious, I really want to know!
