When I went home for lunch today, my usually very energetic flock of 12 hens come runnin' at me, but today they were pretty subdued. I took some treats out to them, and noticed one was walking funny... like her legs were all rubbery. They were sort of sticking out to the sides and she was wobbling pretty badly. So I picked her up and did an examination. No feathers missing, no sigh of attack at all. Could her legs have been asleep? Because when I put her back down she seemed fine. Has anyone else ever seen this in one of their chickens?
