She will spawn with a male when they are both ready and the conditions suit them. If they don't spawn within a resonable time, (3 or 4 weeks) her body will/may reabsorb the ova to no ill effect.
by laying eggs I think they will get pregnant and lay eggs.
No. Budgies are birds. Birds do not get pregnant, as reproduction is done through the laying of eggs. The eggs take about three weeks to form properly in the body, but this is not called "pregnancy". They look the same when they are laying eggs as when they aren't. In other words, birds don't "hold" their eggs inside their bodies and show a big belly to indicate that eggs are on the way. The egg shell is the last thing that develops right before the egg is laid, therefore, a hen doesn't "show" in the sense that human women "show" when they are pregnant.
No, ghost shrimp do not get pregnant as they are not mammals. They reproduce by laying eggs that hatch into larvae.
Frogs don't get pregnant in the same way mammals do. They lay eggs externally in water and the female releases eggs that are then fertilized by the male. You won't see a pregnant frog in the traditional sense but rather notice them laying eggs in clusters in the water.
usually about 18-20 weeks old before they actually begin laying eggs. -<3-
Guppies, mollies and platys become pregnant and give birth to their young, live, instead of laying eggs.
No, laying mash does not make eggs infertile. The fertility of eggs is determined by the presence of a rooster to fertilize the eggs before they are laid by the hen. Laying mash is a type of feed specially formulated to provide the necessary nutrients for hens to lay eggs consistently.
about 7-12 weeks
You don't. Parakeets are birds. They do not get pregnant, as reproduction is done through the laying of eggs. The eggs take about three weeks to form properly in the body, but this is not called "pregnancy". They look the same when they are laying eggs as when they aren't. In other words, birds don't "hold" their eggs inside their bodies and they do not show a big belly to indicate that eggs are on the way. Birds which are getting close to laying an egg become more lively, excitable and playful. You need to provide it with a nesting box in its cage.
Frogs do not get pregnant. They lay eggs that hatch into tadpoles then grow into frogs.
Giant African Land Snails (GALS) often hold their eggs for 3-6 days before laying them 1-1.5 inches deep in the soil.
Yes! Crabs reproduce by laying eggs.
