I have a female and two male call ducks in a pen outside with a small pond. The female is sitting on eggs. When they hatch can I just let her take care of them? She has the eggs in a big tupperware container that I flippped over and cut a entrance hole in. Will she keep the babies warm enought? Is it OK to let the two males stay out with her and the babies? Do I have to put out special feed for the babies? Need some help to figure this out.
