I have a Muscovy hen that isn’t well. She is an older hen, but has been healthy up until now. She has been slow and seemed to have trouble breathing the last couple days. Now she defiantly has laboured breathing, gurgling, coughing or sneezing a little bit, small amount of fluid from nostrils and mouth. The right side of her chest looks enlarged. I know she obviously has an infection and fluid build up that can be caused by a number of issues but I cant find much info. This sounds stupid but… do ducks have crops that can get sour or impacted?? Or is the fluid on her lungs? Have you ever experienced this? Any idea what I can treat her with that doesn’t include a vet. Any insite would be appreciated!!
