I aam new to ducks. I have 2, 9 month old Cayuga ducks that are currently laying. One of my ducks recently starting having difficulty walking. Her leg points straight back and shakes then comes back down when walking. She seems stiff. Her wings are held tight to her body and she no longer flaps them. She has been loosing weight. She does eat but it sems difficult for her and needs extra water to get things down. She was my quacker but now she no longer quacks. The vet is not sure what's wrong so she put her on some steroids but i dont think it's helping. Does anyone have any ideas? I've googled the symptoms but nothing seems to fit. I'm at a loss. Please help!
