No she was never dewormed. The stool was negative per the vet. She was healthy and looked great and one day I went out and saw her sitting in the run while the others were scratching and foraging. I thought she was just resting, but then I noticed she wouldn't try to get up when I approached like they do when they think I am bringing a treat. When another chicken went over and pecked her she ran screaming into the coop. She had been hanging in the coop rather than going outside for a few days and preferred to stay next to my son when he cleaned the coop. Because of my spinal surgery I hadn't been out for a little while so I just thought she was warming up to my son as he said I think I have a new friend. so I think whatever it was was going on for a few days before I found her sitting in the run with her tail in the air and her head lowered. I think, looking back, she was keeping her balance because when she stopped standing on her right leg, she would push with her left leg and when she started rolling forward, she would lift her tail the same way to try to keep from falling over which just made her fall forward more and I would have to right her and support her with rolled towels. She never lost her appetite, so I would prop her and place her food in front of her. Her crop initially was fine because the vet checked it, but then it started not emptying and that is when I started with the water only and tube feeding which seemed to do the trick and gave her more life. The vet had her on a broad spectrum antibiotic for a week along with an anti inflammatory with no real improvement except for a little more spunk about 45 minutes after the antiinflammatory. That is why I asked if I could continue that as long as I thought she might be having discomfort. Her feet shook a little before which made me think she was in pain, but when that stopped, I stopped the anti-inflammatory. She had probiotics and electrolytes in her water. When she did perk up with the tube feeding, she was able to stand on both feet and take a few steps, but would have to right herself by putting her wing out to push up when she tilted. The vet said to start giving her food again if she was able to eat it, and because she had improved, she dove into the feed as if she was famished. the next morning she was terrible and her crop was not emptying again and it was downhill from there. right now she is sleeping quietly and occasionally will wake up and cluck and preen her feathers and then go back to sleep.she is propped up on towels and I change the pad under her when she soils it. she doesn't seem uncomfortable right now.
