Hello, I helped hatch one of my ducklings. He was doing really well & then I noticed one of his eyes had a white film on one end. Last night, I sprayed “drug-free” nasal saline solution (only ingredients are water, salt & baking soda) to his eye. This evening his other eye has the same problem and he’s weak now, won’t eat or drink water. I purchased Terramycin and applied it to both eyelids. Any advice?
