Hi there, Help needed!! I have 2 pet runner ducks, that are both usually quite vocal and happy. Today tho, the female is not right She's quiet, is moving quite slowly, appears hunched and her feathers are fluffed out. She hasn't eaten anything and is pooing a thin white gooey substance. I have checked her over for any injuries, nothing seems wrong. We have an enclosed garden with high fences and they get locked up in a house at night. Any ideas what could be wrong ?
