I have a new duckling 3-4 weeks old and it nibbles on everything! Is this normal? Why does it do it? It doesn't hurt or anything (yet), I'm just curious.
Ducks are foragers - they find much of their food by nibbling around leaves, twigs and rocks, and in the mud - so it is an instinct they have that has served them well for thousands of years.
I have often thought, too, "just like a toddler - everything in the mouth!"
