This is my second post about my duck Penny. I'm just wondering if anyone else has ever had a duck with this issue, and what the outcome was. I noticed bleeding from area above her wings a few weeks ago. The skin under her feathers was raw and red. I took her to the vet and he said he wasn't sure but could be necrotic dermatitis or gangrenous dermatitis. He said she had little scabs on other places on her body, and maybe she was immunosuppressed from a virus she had at some point. He put her on an antibiotic, which she took for almost two weeks. The area initially bleeding healed, but then seemed to move with a new area of raw tissue popping up every few days, just when I thought maybe she was going to get past this. Two days ago I thought she was pretty much healed up and then yesterday she had an area that was bleeding and looked worse than ever. I got a different antibiotic from the vet yesterday and we're now trying that. I'm really mystified because everything you read about the above mentioned diseases indicates that birds die quickly. Penny continues to eat and drink as normal. She's never lost any feathers or down, still loves treats, and loves to get in the pool, although I've been limiting that as I don't know whether it makes her wounds worse. I know the raw areas are sensitive and probably hurt her. If anyone has any knowledge in this area, I'd love to hear from you. I've scoured the internet many times and just can't find any disease that seems to fit what she's experiencing. I don't want her to suffer, and if this is a lifelong condition, will probably put her down. With this new antibiotic we're not allowed to eat the eggs for 30 days from when she finishes it. That means tossing all my eggs since I don't know which ones are hers - arghhh! But small price to pay if she could get better. Thanks all.
