I'm having a serious problem and have noticed others on here as well describing the same symptoms. No one is sure what could be wrong with the chickens. I've had one die and just found one that has the same symptoms but literally hit her so fast it's scary. She was fine this morning and tonight horrible. Their wobbley, no control, eating but not much, same with drinking. The one that died went through this for several days before she was unable to even walk or hold her head up. This other one hit her within a 8 hr period and is at deaths door now. I'm planning on being at the vets door step first thing in the morning. NOW..my question to everyone is, what is everyone feeding? Alot of people on here that are having the same symptoms and saying they feed Purina. I'm wondering if this might be a problem. Please help me..I'm really worried now!!
