it either means there dead or their werent anthing in them the first place or they havnt got enough warmth
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.
Swan eggs develop outside the mother's body. After the female swan lays the eggs, she incubates them by sitting on them to provide warmth until they hatch. The incubation period typically lasts about 35 days, during which the embryos develop inside the eggs.
Mute swans hatch from eggs, not born alive. The female swan typically lays a clutch of 5 to 10 eggs, which she incubates for about 35 days before they hatch. Once the eggs hatch, the cygnets are relatively precocial, meaning they can swim and feed themselves shortly after emerging from the eggs.
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.
Some will but the hatch percentage will be very low.
Eggs in cartons are not fertilized and will not hatch. You can try though!
Swans reproduce internally. During mating, the male swan (cob) fertilizes the female swan's (pen) eggs inside her body. After fertilization, the female lays the eggs in a nest, where she incubates them until they hatch.
Yes.
Lay eggs, (of course! they're birds) Swans have their babies by laying eggs. Birds do not give live birth like mammals do.
nothing.except that the eggs may get cold and die iff the duck does not return.
