After mating, female penguins lay eggs, which are then incubated by the males. During this period, the female penguins go off to feed and build up their strength for the upcoming chick-rearing process. Once the eggs hatch, both male and female penguins take turns caring for and feeding the chicks, protecting them from predators, and teaching them how to survive in the harsh Antarctic environment.
So, while penguins don't stay mothers in the traditional sense, they do exhibit remarkable cooperative parenting behavior, with both parents actively involved in raising their chicks and ensuring their survival.
