In bi-parental care, the male provides food and the female is a caretaker. Both ensure the survival of the offspring. The female may care for her young by covering them to keep them warm, shielding them from the sun or from rain and guarding them from predation. The male may also feed the female, who in turn regurgitates the food to the chicks.

[6] Ethical concerns are most often attributed to the presence of a fertilized embryo within the dish, given the fact that the egg has not yet hatched nor been given the chance to hatch. [7]
A female mallard duck incubates her eggs. Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The day after they hatch, the precocial ducklings climb to the opening of the nest cavity and jump down from the nest tree to the ground. The morning after hatching, the hen will leave the nest to feed and make sure it is safe for her chicks. When she decides it is safe, she uses a maternal call to call the chicks out.
