I have a year and a half old chicken. Thursday morning I noticed she wasn't moving around as usual.She started making a girl fling noise and had discharge. In this area, many chickens are getting sick. People say because of the rain, they are getting bronchitis. I put Vet RX on her and started antibiotics with all my chickens. Some were sneezing. So far, they seem ok. If has been 3 days and she is not eating and I am giving her water every 30 minutes. She just stands are lies down. Does anyone have suggestions or experienced this? Is there chance for recovery at this point? Any help would be appreciated.
