Noticed this morning that one of my five hens can barely walk.... she sort of falls over with each step and is primarily just sitting there. I checked her over pretty good and did not see or feel any obvious injuries. I don't know what to do next and I am worried she could be suffering. Any thoughts, ideas or suggestions would be appreciated. Thanks!
I would wonder if she is laying internally or may have egg yolk peritonitis, especially if she hasn't been laying, or has a history of soft eggs. Cancer can also be common in chickens. Has she been exposed to any new chickens recently who may be a carrier of Mareks disease? It's good that you have a vet that will see chickens. Hopefully they will help with her problem.
Long story short: An x-ray did not show an egg but did show a very enlarged liver, pressing on the spinal cord, thus the interference in her ability to walk. The possible reasons for the inflammation were only educated guesses. A few treatment options were considered ( anti-inflammatories and antibiotics, a blood test for Marek's) but in the end, for various reasons, I decided to euthanize her. She was a pampered girl and lived a good but short life. I am sad but am comforted in knowing she is no longer suffering.
