I want to know some information about the health of ducklings.

Ducks can't leave their mothers to raise ducklings. First, prepare a paper box with newspapers in it. Newspapers should be changed every day. If it's a duckling whose wings haven't grown yet, feed it with gruel and pay attention to feeding it several times. Bathe it every day. Just put it in a basin just filled with water and it will bathe itself. When it is bigger, put some screws in the water (the screws should be broken with a shovel head).
