The ducklings hatched last night and were dry this morning so we decided to put them into the brooder with the older duckling who hatched a few days earlier. The oldest has a habit of sitting in his water bowl while he drinks and eats, and the younger ducklings are following suit. My concern is that since they were hatched in an incubator, they didn't have a mother to put oil onto their feathers after hatching. Even though the brooder is at 90 degrees, will that prevent them from getting cold or waterlogged? The water in the dish is very shallow, but I'm still concerned about them getting hurt since they're so young.
