Hi, we’re new to raising ducks and one of our ducklings started to limp yesterday. There’s no obvious signs of anything wrong. Her siblings are fine and they’ve all been receiving duck feed since we got them 2 weeks ago and we regularly give them peas. She’s spent a lot of time either floating in their pool or lying down (and sometimes getting trampled). Wondering if we leave her in the water and/or move her to a crate to rest her leg? If we crate her, does she stay in their pen so she’s not alone? Should we also increase their niacin?
