If ducks are regularly fed bread, ducklings will not receive adequate nutrition for proper growth and development.

The riddle provides a little bit of levity during a pandemic, which we all need from time to time. Others say it’s a sure sign that there’s another duck under its wing and part of the joke. Some argue that you can’t see the duck at all and it shouldn’t count.

You can just barely make out a blob on the duck’s wing that is different from the other ducks in the photo, indicating the presence of a second duck. The duck on the far right in the middle row is the most questionable one and the source of some debate - it’s why you might see some people saying the answer is 15 and not 16. On the third row on the far left, there are two ducks superimposed on top of the big duck. On the middle photo in the middle row, there’s another small duck by the duck’s feet. On the far right in the top row, you can see a tiny duck by the large duck’s feet. The middle top one shows two ducks side by side, which is just like the far left duck on the middle row. You can see where the ducks are located in the photo above.
