i have two indian runners. They are four weeks old. One is very active, vocal, and a big eater. The other is the opposite. She prefers laying to standing. She's slightly smaller (always was). She's not as chatty and has a quieter voice. If we go to the yard, the other duck will run around and nibble at stuff, and Vivian will just crawl into my lap and hang out there. She also seemingly eats less. However, she is very active in water. She loves bathing. Always doing it in her water bowl. She dives back and forth in her little pool. While my chatty bird is not so enthusiastic about water. Do y'all more experienced folks think something could be wrong? Or is it just that she has a lazy personality?
