mostly birds
All birds hatch from eggs, no matter the species.
all eggs have an incubation time, these times vary for different species. You can not rush this time. The eggs will hatch when they are ready and the parents will know
It depends on the species.
No,only monotremes hatch eggs.
Some species do. The species that do require their eggs to have several weeks extra of maturity after they are laid before they can hatch. Other species are ready to hatch almost immediately after they are laid.
Sure. The male of any species doesn't lay eggs. but girls???
Bad eggs don't hatch into missingno
Mantis eggs typically take about 3 to 6 weeks to hatch, depending on the species and environmental conditions.
Bird eggs are laid at different times, so they usually hatch first laid first hatch and so on. This is more common among raptors. For other birds, embryos develop when the egg is incubated, and birds will delay incubation until all eggs are laid so that all the chicks will hatch at the same time.
the southern black koi fish males sit on the eggs until the eggs all hatch only if the female brings food to them every hour or he will eat them all.
It all depends on the fish. Some species often guard the eggs and some species will eat. Also remember that all fish have their own traits and characteristics. What one fish of a species does another fish may not do.
Yes, all spiders lay eggs. They typically produce silk egg sacs to protect their eggs until they hatch. Each sac can contain hundreds of eggs, depending on the species of spider.
