Penguins lay eggs, they do not get pregnant.
Penguins are not born; they are hatched from eggs.
Penguins are birds, they lay eggs, is your question haw long are the eggs retained?
There are many wild birds, and they are very different, so the hatch (note - hatCh) times vary depending on the species. For example, Ostrich eggs take 40 to 45 days of incubation to hatch, the Emperor Penguin takes 64-67 days, and most hummingbirds' eggs take only 8-12 days to hatch. Of course, if an egg is not incubated properly or it is not fertilized, it may never hatch -- however, it most likely could make a very nice omelette or souffle if it hasn't been sitting around too long :>) There are many wild birds, and they are very different, so the hatch (note - hatCh) times vary depending on the species.

Most eggs take about 34-35 days to hatch. The first egg laid takes about a day longer to hatch than the second egg (33 days). They hatch about 1.5 apart.
It takes 2 to 3 days for the eggs to hatch.
Monarch eggs taker about 4-5 days to hatch.
that does not make sense
Cockatiel`s eggs normally hatch after about 19 days.
They don't lay eggs.
Egg size and weight varies with species. From the records of SeaWorld's successful penguin breeding programs, emperor penguin eggs measure 11.1 to 12.7 cm (4.4-5 in.) long and weigh 345 to 515 g (12.1-18 oz.), and Adélie penguin eggs measure 5.5 to 8.6 cm (2.2-3.4 in.) long and weigh 61 to 153.5 g (2.1-5.4 oz.).
