My beautiful baby girl (8 month old white Campbell ) is acting odd. She keeps pointing her tail down, almost like a dog tucks it's tail between its legs. And can be a bit stroppy. Separately she also has a thinning patch underneath her top layer of feathers where her feathers look matted with a lot of pin feathers but it looks like there are a few feather stumps/shafts that have black fuzzy things in. At first i thought they were bugs but they don't move then i thought it was congealed blood but now i just have no idea. I've mite powdered her just in case but she doesn't even scratch. Any ideas on both issues? She otherwise seems fine. I'm probably just being overprotective but i worry!
