I've noticed one of my young hens (astroloupe, hatched spring 09) had lost a few back feathers 2 days ago. Yesterday, I checked on her and found all sorts of milky stuff hanging on the back feathers - looks like drippy poo? She's still active, not as much as my other hens, but she did come out of the coop this morning for corn scratch. I took this picture this morning. I'm super worried! Should I bring her inside? Leave her alone? My other birds (20 chickens, turkey, ducks, and goose) are all fine, eating, laying, etc. I've attached a pic, Any ideas would be much appreciated.
