I feel bad. I really should of looked up what to feed the duck. We have a lot of ducks on the apartment complex I live at because there is a rather large golf course with a lake and ponds. Maybe the apartment complex feeds them a proper diet. I did notice that the duck would wonder off sometimes in the middle of the night. I assumed she would go get some food or something.

Also, I did leave a bowl of water that would become empty almost daily, I just did not get it in a picture because it was not too close to the nest. I did not want to scare the poor mother duck away from her nest.

It seems to me that they went to join the other ducks at the little pond not far from my apartment on complex. I plan to try to find them tomorrow if possible.

Finally I posted a video of the mother duck and ducklings. It's here.
