Some hens do have a harder time keep clean, haha. With a bloated abdomen droppings do stick more.The first picture is her sister Petunia. She has the dropping on the butt feathers as well but is free ranging still and has bright cone so I don't think that is related. Compared to petunia, no-tail-a has a much puffier abdomen. see right picture. Im not sure why it flipped it.
