Itās not a lost cause. Keep the duckling warm and give it time.Right little duckie is still alive this morning! heās more struggling around but his eyes are still closed ?! Also obviously the major issue that this goo etc is still majorly attached to him. It also smells so obviously Iām worried it will give him an infection. Can it all be tied off somehow so it drops off? Or is this really a lost cause ??
Like @Debbie292d said, the umbilical will shrivel up and fall off on its own. When that does happen, you can put some antibiotic ointment on the navel. I did that several times a day.
If you think itās eyes are sealed shut by dried goo you can gently wipe them with warm saline.
