Mine do get broody. I would never let ducklings near any other big ducks except momma. Drakes have been known to kill ducklings. Ponds/pools aren't necessary, but do help ducks spread their oil that keeps them warm and dry. They absolutely must have water any time they have food and they must be able to dunk their faces to keep their nares clear. Ducks love to forage. Be it in soil, mud or gardens. I have to pen off my gardens to keep them out... They like the same veggies I do!
