I have a three year old BO Hen who has recently lost her voice. She sounds just like a person with laryngitis. Her face and comb do look a little more red than usual, but otherwise she is the picture of health. Just finished a molt, starting to lay again, is healthy feeling and robust. We are going away for 5 days at the end of the week. I have built them a temporary pen in the garage and someone will be checking on them half way through. Thoughts? Should I treat with an antibiotic just in case? Something water soluable is perferred.
