how often does an ostrich lay an egg?

In captivity, females may lay as many as 100 egg in a season, although 20 to 40 are more common. \nIn North America, the breeding season is from February to October

The largest egg ever discovered was laid by the now extinct, flightless elephant bird. This 13- by 9.5-inch (33- by 24.1- centimeter) egg held over 2 gallons (9 liters) of liquid. That's eight times as much as an ostrich egg.\n\nThe ostrich egg is the largest egg in the world today.\n\nThe kiwi bird lays the largest egg in proportion to its body size. It would be as if a human gave birth to a 43-pound (19.5-kilogram) baby. No wonder the female lays the egg, and the male has to sit on it.

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.

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.

If 1 1/2 chickens can lay 1 1/2 eggs in 1 1/2 days, 1 1/2 chickens can lay 1 egg in 1 day, while 6 can lay 4 in one day. Therefore, in 4 days, 6 chickens can lay 16 eggs.

Yeah, not poisonous, ostrich is hard to crack.\n\nDidnt snakes lay eggs too? dont remem

There are three living genera of Monotremes, which are the group of mammals that lay eggs:\n\nThe Platypus (Ornithorhyncus) of Australia\nThe Short-nosed Echidna (Tachyglossus) of Australia\nThe Long-nosed Echidna (Zaglossus) of Australia and New Guinea\n\nThere used to be a lot more species of egg-laying mammals, but these are the only ones that survive today.

Depends on the bird. Usually it is inversly proportional to the size of the cache of eggs. Chickens for example lay a great number of eggs because they are flightless and pretty much defenseless. Mortality is high so the species compensates with prodicious egg laying. Interestingly this makes them an excellent livestock choice which has certainly contributed to the survival of the species.

The egg.  Reptiles were around a lot longer than chickens, and reptiles lay eggs.

If you only have one canary then it can not be fertile but if you have a male and female then you may see some babies soon.If they arent fertile she will throw the eggs out of the nest herself.

It varies greatly from animal to animal. Smaller mammals, such as cats, have a somewhat similar discharge following a period of being "in heat". But many animals exhibit mechanisms with no resemblance to the human counterpart. Snakes, for example, undergo a prolonged period of molting, shedding layer after layer of skin until they occasionally die of exhaustion and malnutrition, or burst into flame. Many species of bird, chickens included, lay eggs upon reaching maturity, even when there is no mate to fertilize them. This, however, is widely regarded as a sin in the animal kingdom, and is condemned by the bird pope.

yes- the eggs are not always visible

Once a year.  They grow them in the summer and fall, and shed them after mating season.

Yes Penguins lay eggs\n\n1. Eggs may be white to bluish or greenish. The shape varies among species. In Humboldts and Adélies the egg is more or less round. In emperors and kings the egg is rather pear-shaped, with one end tapering almost to a point. \n\n2. Egg size and weight varies with species. From the records of SeaWorld's successful penguin breeding programs, emperor penguin eggs measure 11. 1 to 12.7 cm (4.4-5 in.) long and weigh 345 to 515 g (1 2.1-18 oz.), and Adélie penguin eggs measure 5.5 to 8.6 cm (2.2-3.4 in.) and weigh 61 to 153.5 g (2.1-5.4 oz.). \n\n3. A nest of eggs is called a clutch, and with the exception of emperor and king penguins, clutches usually contain two eggs. (Emperor and king penguins lay a single egg. ) A clutch with more than one egg presents a better chance of at least one chick surviving (del Hoyo, et al., 1992). \n\nPenguins dont have knees.\n\n1. Penguin legs are short and strong. Feet are webbed, with visible claws. The legs are set far back on the body to aid in streamlining and steering while swimming. This placement also causes penguins to stand vertically and walk upright (Marchant, 1990). \n\n2. Penguins walk with short steps or hops, sometimes using their bills or tails to assist themselves on steep climbs (del Hoyo, et al., 1992). The maximum walking speed for Adélie penguins is 3.9 kph (2.4 mph). Emperors and kings walk slowly and do not hop. The maximum speed for emperors is 2.8 kph (1.7 mph). Some species, like the rockhopper, jump from rock to rock (Miller-Schwarze, 1984; del Hoyo, et al., 1992). \n\n3. Antarctic species can move much faster over ice by "tobogganing" on their bellies, using their flippers and feet to help them move along (Simpson, 1976).

We raise chickens and as far as I know you cant really increase the size of the eggs, the chickens start laying after about 6 months, the eggs are small, and then begin to grow larger as the chicken grows larger. Hormones and such can speed the process of the chicken growing, therefore, theoretically increasing the size of the egg

Egg is laid in a day ... If fertilized, the incubation period (laying till hatching) is around 3 weeks.

From the union of a sperm and an egg.  That or the stork.
