I have two ducks. I don't think what's going on is contagious because only one of my ducks is sick and the other is fine. Here are the symptoms of the sick duck: slow and weak, quiet quacks, stuff in eyes (one eye, only noticed this happening today.), losing weight, and I've seen her shake her head a few times. Also, possibly her feathers aren't as well as they use to be near the ends, but she also has been using them to balance when she trips over tall grass so maybe it's from the ground. I don't know what's going on and I'd love advice as well as treatments to help bring her back to her happy self. I'm so worried! EDIT: She is getting weaker. I am giving her charcoal and trying to flush any possible toxins she could have ingested. I should add that she stopped laying. I know that might not be an important part of whats going on, I thought I should mention it anyway. Does anyone know what could be going on? Does this sound like any known sickness? Will she survive?
