This is my five-year-old chicken named Dakota. I came out to check on them this morning and she was sitting in her nesting box which she usually doesn’t do unless she’s laying in an egg and when I open the doors to let them out she wouldn’t come out , so I picked her up to check her out and she has poop that’s the color and consistency of egg yolks all over her bottom and she’s very lethargic and puffed up. Does anyone have any ideas what it could be?
