I took 2 hens to the avian vet yesterday. One has a big swollen abdomen and just looks messy. I thought she was egg bound (but couldn't feel any hard masses) or had peritonitis. The second was wheezing and coughing although she had no eye or nasal discharge. Two separate coops and no other birds exhibiting the same symptoms. Here are the diagnoses: Hen 1 - abdominal hernia. She can live and still lay for years with her hernia. And even though she looks pitful, she feels fine. Surprisingly common. Hen 2 - aspirated something and it's stuck in her trachea, probably a little piece of bedding. Also a common occurance according to the vet. She should cough it up but it can cause a bacterial or fungal infection so she got a big antibiotic shot and is now on antifungal pills....don't you love pilling a chicken?! Just thought I'd let you know what I learned. I was surprised at how wrong I was in assuming the worst.
