Saturday morning I found one of my 7 chickens spread out on the couch not moving. It seems like her legs were partially paralyzed because usually she doesn't let me touch her. I brought her inside in a bunny cage and things have just gotten worse. Her body keeps having spasms or seizures. Sometimes her head will go straight forward and her feet will come up over her head. I can feel her entire body tensing. It is fairly Non-Stop. I am giving her the infant vitamins and rooster booster and the silver antibiotic Stuff. Plus electrolytes in her water. I have no idea what it is or what else I can do. Please help! She is almost two and a half months old and an Easter Egger.
