It depends on the length of time. The duck will leave from time to time to feed or to continue mating (a mallard can hatch ten or more ducklings at a time). Before she vacates the nest, she will cover them heavily with feathers to provide insulation to keep the eggs warm and to keep them camoflaged from view until her return. Once she starts sitting, if she vacates the nest without covering the eggs, it most likely means she was scared off the nest by a predator, in which case she will need to return soon or lose her brood.
There is nothing you can do about this. The eggs will die.

I would not do anything. Do not touch the eggs, or the mother may never come back again. The mother may come back, some birds tend to leave there eggs for a while, but then come back later with something for their nest or the baby birds.
Eagles
It is called Mother Bird.
well when a mother possum leaves she bings her babies with her because she dosnet want to leave them behind......
No. She lays the eggs and then leaves. The eggs hatch and the babies are on their own.
The mother bird knows instinctively how to protect her babies from predators.
She doesn't. She lays them in her (already made) nest and keeps them there.
# it takes about 1-2months for a baby bird leaves its nest.
In the wild yes it is possible I dont think so in captivity but its best not to bother the babies to much or the mother wont come back at all.
Must be fed by the mother bird
The mother bird will flail around, flapping her wings and making a great deal of noise. Some birds pretend to have a broken wing, in hopes of getting the predator to follow them and leave the chicks alone.
Since i have no empathy for pests like mice id dispose of them.
well it depends on what kind or what the surounding's if the mother bird feels its not safe she'll move them.like for example there's a fallen tree or the tree will fall the mother has a speacil feeling in her body.or there's a hawk or a bigger bird then her.she'll move her babies some where more safe for her young because shes like your mother SHE LOVES HER KIDS..........!!!!!!!!!
