HI... My hen has a huge and swollen abdomen and the feathers have disappeared where the belly is protruding. There were posts regarding this but are about 5 years old. I am wondering if there has been any developments or information updates regarding this condition. The previous posts didn't provide too much in the way of remedies but it does sound like a common condition in hens 2+ years old. Can anyone help regarding this? Thanks so much. I hate to see my girl in this way. Judy in Pemberton.
