I was just given 3 abandoned runner ducklings, about 2 weeks old. Mom disappeared. They obviously have never been handled and are terrified of the sight of me. Their reaction is heart-breaking and I worry that they will injure themselves. They are inside, in a tub, under heat, eating/drinking ok as long as they don't see me. I've raised a number of ducklings but they were just days old when I got them, no fear issues. Any suggestions/advice on taming these babies and reducing the trauma to their 'duckling psyches' ? Thanks.
