I've a sick hen. We think after reading posts she has coryza. I am not interested in culling my flock. I bathed her, dried her, have given her vetrx. All my chicky babies get probiotics and oregano oil in their water. She doesn't eat or drink by herself but she has perked up and sounds better. I've been dropping water down her throat. How often and how much water should I give her? Thanks for your time..
