I know they need water, so I filled a bathtub and put it in the water and gave it bread. Downy waterfowl are protected by oil from their mother's oil gland. They do not have the ability to generate this oil on their own. If they are placed in water they cannot get out of, they will eventually become waterlogged and die. Bread is a common misconception.
Adult birds have gravel in their crop that allows bread to be broken down for digestion.
Young babies do not have the benefit of gravel and, as a result, the bread will become compacted in their crop. This can cause death. Q. I brought a baby bird into the house and turned on classical music to soothe it. Baby birds are wild animals and as such have no experience with, nor need for music. This will, in fact, frighten them and add to their distress.
