I had a hen that could not stand or walk and was getting badly harassed by the rest of the flock. I felt awful so i put it in the hen house alone and hand fed and watered it and nothing changed it just got worse. I was ready for it to die when i seen your site and most were saying it was not going to make it. thinking it was an ear thing because if the balance issue i tried a hail mary and used the ear drops the pharmacy gave us for my sons swimmers ear. Wow it worked! Five days later its with the rest of the flock and gaining weight. Now Im no vet and dont even know if the drops were what saved it but its worth a try if you are experiencing
the same problem. Very happy to read your forum.
