it either means there dead or their werent anthing in them the first place or they havnt got enough warmth
Not that much initially. If all swans always laid one egg, fewer swans would hatch, and fewer swans would reach adulthood. Eventually this would probably lead to swans becoming fewer.
if a male swan mates with a female swan she falls preggie than she lays eggs then her eggs hatch and then baby swans come out so a baby swan is a baby of a swan
Swans are not mammals, therefore, they lay eggs and sit on them until they hatch.
Nothing, Because This Is Impossible. All Eggs Will Hatch At A Different Time.
We have swans in the lake by my house. We have been here for three years and each year, its been the female that incubates the eggs exclusively.
Eggs in cartons are not fertilized and will not hatch. You can try though!
Some will but the hatch percentage will be very low.
Yes.
Lay eggs, (of course! they're birds) Swans have their babies by laying eggs. Birds do not give live birth like mammals do.
well, actually nothing. Your parakeet may also lay eggs but, the eggs AREN'T going to hatch. :(
nothing.except that the eggs may get cold and die iff the duck does not return.
they get eaten by other animals
swan can lay about 5 to 7 eggs
