I have a very small white female call duck who has been acting sickly ever since I brought her home. She lays around most of the day, she breaths very heavily, her eyes aren't as bright and open as my other ducks and her vent is dirty. I've been putting electrolytes in the water everyday, but she hasn't gotten any better and it's been a couple weeks. The other two ducks I brought home with her are the perfect picture of health. I just don't know what to do...I could take her to the vet but I don't have a vet that specializes in poultry anywhere near here so she'd be going to the local vet... Anyone have any ideas?
