Hello, recently one of my six chickens started sneezing, coughing, runny nose, diarrhea and sounded hoarse. This was Thursday morning. I separated her right away from the flock and brought her in set her up in a cage. Started her on amoxicillin, ACV water and interchange with electrolyte water. Today is day 3 of treatment. She sound much better. All previous symptoms are gone and she layed her first egg today. She seems energetic and wants to come out. When should I introduce her back to her flock? Thank you!
