What is the illness called when a hen loses her balance? About two weeks ago I noticed one of my girls seemed to have been attacked by something from the back, missing a chunk of feathers and most of her tail. It may have been a run-in with another hen as there were no signs of any outside attack. Anyway, she seemed fine, just extra snuggly (she's a real cuddle bug), but yesterday I noticed she's a little bit wobbly on her feet. And today she's a bit worse. She's still running around the yard and interested in everything, having dust baths and foraging for food, but she's definitely having balance issues and I want to catch this before it gets worse. Any thoughts??
