Hi all. I'm having the same problem with one of my hens. nearly 3 yrs old, Amercauna. Dirty, poop stuck to feathers around her vent (just as previously pictured). Soaked her in warm epson salts and removed nearly all the poo. After keeping her in overnight, let her back out. Not as active as normal. That was last week. Today, noticed her vent feathers are again packed with poo. Back inside and soaked/cleaned. Keeping her in my laundry room, floor covered with newspaper. Noticed she produced runny poo. Vent appears normal, no signs of inflammation. She feels thin-bony breast-can feel her sternum. Worried. Have provided water with Corid. Any further advice or info much appreciated.
