I thought my duck was getting fat from being broody and sitting on the nest all summer. But today I picked her up cuz I noticed she's moving slow and discovered that this fat pouch that I thought she had feels more like squishy water I don't know what it is or why she has it so I'm coming to you for some answers if you got them. I looked it up and the only thing I can find about anything similar is called water belly and I really hope she doesn't have that.
