In the Brooder
A few days ago I noticed that my 15 week old Rouen duck, Quacken, started to have sagging in her underbelly area. It is slightly becoming more visible and saggy as the days progress. She is not showing any signs of distress, she's eating, drinking, swimming, and playing just fine. She has a sister that has not shown the same sag. Any idea what could cause this as she is not yet old enough to lay?
