Several days to several weeks.Temperature and water movement will also affect the period of time for fish eggs to hatch.

Though it is true that there is little parental care in most fish it does exist it varying degrees.\n\nIn most fish it doesn't go much further than finding a good spot to lay their eggs. In a few cases a fish will defend the place where the eggs are laid. \n\nIn sea-horses the males actually hold eggs in pouch on their tummy until they hatch at which point the male "gives birth" (there is no more care after this).\n\nIn general though parental care is minimal at that is why fish lay so many eggs. Biologists call this an "r" strategy of breeding (lots of young, no parental care) as opposed to a "K" strategy (few young lots of parental care - like in humans). Animals range the whole spectrum between these two extremes.

yes it does, and if you want to show off and try something cool, pour salt water into a beaker or glass, then pour fresh water on top of it, then place an egg in. It will "flink"

whenever you can find the time!   the fish are always in the water.  you only have to locate them and find out how to entice them!

put two 2s facing each other and you will get a tiny fish ... yes you are correct :)

The eggs are nourished within the ovaries, and each month one fully matured egg is released. A mature egg has undergone a process of cell division that gives it 23 chromosomes -- just enough to match an equal number of chromosomes from the sperm. Once an egg is released from an ovary, it's pulled into one of the fallopian tubes leading to the uterus. But one of the 20 million to 200 million sperm released by the man has to catch up to that egg soon: If the egg doesn't encounter a healthy sperm, it will perish in 24 to 36 hours. In that case, it disintegrates and flows out with your period. If the egg does get fertilized, it leaves the fallopian tube and travels into the uterus. If everything is in good working order, it will implant there and begin to develop into a baby.

Baby pigeons are rarely seen as they live in nests and only leave when nearly fully grown.\n\nThe incubatoin period for common pigeons is 17 to 19 days.

Scorpions are among the few arthropods that don't lay eggs. In some, the female can store sperm until she is ready to fertilise her eggs. The fertilised eggs develop into embryos in brood chambers within the mother's body. Nutrients are transferred from the mother's digestive system to the embryos, but not through a placenta like in mammals. "Gestation" is quite long: it can take several months to more than a year before the young are "born". In some, the babies are fully formed but their skin remains white and soft until their second moult. In others, the babies look like fat white maggots with tiny pincers. They only look like scorpions after their second moult, when they get the right shape and their exoskeleton turns dark and hard

54 \n\nas each chicken lays one egg every 1.5 days ie 2 eggs every 3 days and so 6 eggs every nine days\n\nThus 9 chickens will lay 9 x 6 eggs in 9 days

It may be that the stress of producing young is enough to do her in; cuttlefish are not exactly the most hardy critters.  Typically, most species only live about year or so, anyway, so they only go through a single breeding season before dying.\n\nAccording to the amateur breeder/enthusiast listed below, females can lay several clutches of eggs, and can live for months after egg laying.

Little is known about wild emu reproduction, most information coming from captive populations. A male with a harem defends a territory. Females lay a clutch of 9-20 eggs each, April through June. Once the male starts sitting, many females move away, sometimes pairing with other males to lay more clutches.\n\nIncubation and raising young is the male's task. The nest is a shallow scrape usually located nest to a bush. It is simply lined with leaves, grass and bark. In general, 15-25 dark green to avocado-black eggs may be layed in one nest. Incubation may take up to 60 days, depending on how much time the male must have to feed and drink. Chicks are precocial and leave the nest after 2-3 days to follow the male. Young birds are capable of reproduction at 2 to 3 years of age.\n\nLongevity is 5 to 10 years in the wild.

I used to have laying hens about two dozen at any given time. An old gal that got me started said that if you want fertile eggs for hatching, so you are not wasting time using an incubator you should wait about a week. But keep in mind that a rooster will have his favorite hens much like girl-friends. To be more sure of fertile eggs it's best to separate or confine the hens with the rooster so he doesn't have a lot choices with whom to fertilize. Or pick out those hens that you've seen him with and only incubate eggs from those hens. Or you can " candle " the eggs to see if you see the " blood spot " on the yolk. This a sure method to verify a fertile egg, but difficult for the novice to do.

They produce eggs and sperm which they secrete into the water.  They then mix to fertilize the eggs.  They never actually come in direct contact with one another.

The 3 weeks begins after the hen starts sitting on the eggs. It may take her a week of laying before she settles on top of them.  Some varieties of chickens sit about 23 days.  If you listen carefully, you should be hearing little tiny peeps coming from those eggs about 2 days before they hatch.\n\nDo you have a hen sitting on the eggs or are you incubating them yourself?  If you are doing it yourself, and you haven't been rotating the eggs frequently, and if the eggs have not been kept in a moist environment, they may have died.  If you have a hen sitting, her body keeps the eggs moist and warm. Give them a few more days.

no they dont lay egg they carry the eggs in a pouch til they are ready to hatch
