Need advise. My chicken has been sick for around a couple of weeks. She is breathing with her mouth open and making a squeaky distressed call and sometimes comes across like she’s sneezing. She isn’t moving around as much but she’s still eating & drinking (less than before) We took her to the vet on Friday and they gave us some anti-inflammatory (Metacam) which is for dogs the vet says it’s not bird flu and she thinks she is thin. She said she is not hopeful and she thought she had no fight in her. I know she definitely knows best and is the professional however I think she does still have fight in her and she does seem to have perked up very slightly over the weekend.. any advise on what could be wrong or anything to help? We don’t want her to suffer but we also don’t want to put her down if we don’t have to.
