Is there a disease or condition that causes what appears to be fluid retention (or swelling) in the feet, jaw area, and abdomen? Hen eats, drinks, dust bathes, looks for insects, etc. So, she seems normal. Does not seem like she is any pain. Not laying at this time. She is around 1 1/2-2 years old. No new bird additions. But I do have quail penned separately. Any suggestions, tips, or information would be greatly appreciated.
