The baby duck who hatched early the other day died, but now another one has hatched and has this goo stuff hanging from the yolk area! it doesnt look yellow like the regular yolk, dark colored/ like a dirty Goo, its just hanging there and he's trying to get up but walks on it! idk what to do. hes really active, I've heard of bandaging, but how? the goo looks to be to be able to hold in a bandage. Please help. any advice!
