Is this egg yolk peritonitis? This is from my 1.5 year old Speckled Sussex that hasn't completely finished molting yet, though she's close. She has been puffed up for the 2nd day in a row now (it's been in the '20s here), and today she spent most of the day on the roost, puffed up and sleepy looking. Her vent looks normal, but her butt feather look like they had egg yolk on them and it looks like there's egg yolk in her droppings (above). Is this egg yolk peritonitis and not egg binding? I'm worried she'll succumb to infection -- is there anything I can do???
