Hello! We had one of our hens pass on Tuesday. I'm not sure really what happened because she was fine this weekend. Monday I noticed she had diarrhea, Tuesday she stayed in a nesting box so I brought her inside. She had diarrhea, shaking, hard breathing and could really stand up. Any ideas on what it could have been? No other chickens are sick we did have another one die about two months ago but she only was unable to stand.
