I have a 4-5 year old hen who has taken ill. The main symptom seems to be her legs don't work. Her eyes and nostrils are clear, no weird bumps or discolorations anywhere I can find, feathers look healthy. No wheezing or other respiratory issues that I can discern (hard to say, I've never sat and watched a chicken breathe). No cuts or obvious injury. I noticed yesterday she was roosting on the edge of the nest box in the middle of the day, and making weird little distress noises. I was able to easily pick her up (not normal) and examined her as best I could. I've separated her from the rest of the birds and given her water and food. It does not appear she has touched either. She just sits in a heap with her feathers fluffed out. Seems to have trouble using her legs, I tried to get her to stand or walk but she wasn't having any of it. I guess I'll just keep her as comfortable as possible. She's on my side covered porch so is out of the weather, away from the neighbor dog (who doesn't bother them but still), and I check on her frequently. Any other ideas?
