My polish frizzle hen has been showing signs of a possible sickness or injury. She is around 6 months old, and still eating and drinking. We've had her for about 3 weeks now and the symptoms have been the same until tonight. She only moves to get food, water or into and out of the coop only during the morning and the night. When she does walk, she walks lopsided and with her wings drooping slightly. Tonight when I went to shut the coop I found her on her side and twitching. As soon as she was picked up she stopped twitching, but I brought her inside to be safe. There is no sign of visible trauma, discoloration or bugs. None of our other chickens have shown any of the same symptoms. She was brought to us with another polish frizzle hen of the same age who is not showing any of these symptoms. We only have hens, and I haven't seen any of them picking on her. My best guess is that she has a neurological issue or is partially paralyzed but I would like to hear more ideas and suggestions on what to do.
