So I have a pekin hen who lovessss getting dirty. Mud, she lays in it. Poop, she will play in it. She bathes every day but her underside is pretty much stained brown(It looks like she has sat in a heavy smoker's home for years and got nicotine stained haha) but I was just wondering if there was something safe that could help remove the stains? It's no problem to me, she's just so fat and pretty that I'd love to see her shine a bit more. If not, it's perfectly fine. Thanks!
