I have a year and a half old hen that has become extremely thin over the last few weeks. I first noticed she had a problem when she was doing the following: -isolating herself from the other chickens -fluffing up her feathers -looking drowsy -her feces were extremely watery, and when she perched at night, it was like she was leaking throughout the night -her tail feathers are at half mass and she seems to waddle, sometimes more than others -feces on her tail feathers, under her vent -I watched her fall over one day Withing the first few days of noticing the symptoms, I thought she was egg bound, so I soaked her, but I didn't see anything come out besides more watery droppings. After doing the soaks a couple of times over a few days without an egg I tried to see if I could pull something out. It looked like something was attached to her oviduct (?) just inside the vent. I speculated that it could be a piece of an eggshell, but I couldn't be sure. While I felt something inside that I thought might be an egg, it seemed to be too low in her abdomen, and I didn't want to pull too hard (I just had another chicken with a prolapsed oviduct). She seemed like she might have a fever at one point, so I gave her small amount of ibuprofen per a message board. I have been keeping her in a large dog crate in my pantry on and off for rest and so that I can monitor her food intake more often. She is still eating and drinking so I like to keep her free ranging. I added a garlic tincture to the drinking water for about a week (for all the chickens) in case it was a worm issue, but I don't see anything. I've been giving her an electrolyte mixture I made of water, yogurt, salt, baking soda, honey and banana. I was excited to see a solid poop the other day, but they seem to be pretty watery again. We did notice that some of the eggs were thin shelled awhile back, so we started adding oyster shell to the food. We also discovered a few partially formed (i.e. shell-less) eggs which I'm assuming were hers. A few days after the soaks I noticed a portion of shell hanging from her vent when I let her out of the coup, so that became obvious. So far, I have speculated around: egg-binding some sort of crop obstruction egg peritonitus liver problems She free ranges, and eats compost and organic laying pellets. Any suggestions or ideas you have would be great, because I'm at a loss!
