I need some help. My 8 month old duck is paralyzed on left side. This started 8 days ago when I went out to barn I noticed her having trouble walking. I picked her up and brought her in so her rooster boyfriends wouldn't bug her while she was hurt. I have tried everything. Antibiotics, took to vet they gave her steroid injection and vitamin b shots. Vet didn't think it was anything broken as she still had feeling in both legs. Fed her everything the Internet recommended as far as veggies, fruit supplements. She has now lost feeling in right leg. She drags herself around on wings. Every time I think of putting her down I put her in pool and she floats(to one side) happy and splashing. She has a good appetite, drinks a lot, poop is green and looks like baby poop. It's just so sad to see her just sitting there. What could it be? Any other suggestions to try for poor Marley the duck?
