How long does a dove egg take to hatch?

Most foreign doves lay two white eggs, which they incubate from twelve to eighteen days. They feed their squabs by regurgitation as do domestic pigeons, and these stay in the nest much longer than do the young of tame pigeons, which is a -real advantage. Some of the larger species, such as cuckoo and other doves, lay only a single egg at each setting. Thus, the Luzon Bleeding Heart lays two eggs each time, whereas the Bartlett Bleeding Heart dove lays but one. The reason for this difference is not known.

Breeding starts when the female sheds her old skin.  This releases pheromones that attract the male.  They will form a pair bond and hunt together as well as protect 20-50 mounded eggs.\n\nThey reach sexual maturity in 5-6 years and will mate in January.

they live for up to 48 hours on their quest for the egg.  then they will be passed or absorbed once they die.

Put the egg in the middle of a 1 foot square styrene block. \nFit the egg with a parachute. \nput it in strong bottle filled with water before dropping it.

The hen (chicken) came first.  The hen layed an egg and had to sit on the egg in order for it to hatch.  If there were an egg first, how would it have hatched?  Look at it this way: Did God put Adam and Eve in the garden or  sperm and ovum?

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.

If the egg is unprotected then wear gloves & transfer the egg to a make shift nest made up of grasses, leaves, ect & keep it warm in the late evening & night with a thick towel. Around 10am if it is about  78degrees or greater remove the towel. after the baby is born worms & insects hunting will be your job\n\nGood luck

The common pigeon, originally known as a rock dove or rock pigeon, is adapted to nest on natural cliffs, usually on coasts. Its domesticated form, the feral pigeon, has been widely introduced elsewhere, and is common, especially in cities, over much of the world. Modern man's high rise buildings are a suitable substitute for the natural cliffs that these birds need, so essentially every urban area is seen as ideal nesting habitat by these birds.\n\nPigeons breed when the food supply is good — for wild rock doves this might be on a seasonal basis so they usually breed once a year. In cities, feral pigeons can be seen eating grass seeds and berries in urban parks and gardens in the spring, but there are plentiful sources throughout the year from dropped fast-food cartons, restaurant and supermarket trash, tourists with birdseed, etc. In the urban environment, because of the year-round food supply, feral pigeons will breed continuously, laying eggs up to six times a year.\n\nPeregrine Falcons, another original cliff dweller, have also adapted to the big cities, living on the window ledges of skyscrapers and often feeding exclusively on Rock Pigeons.\n\nhttp://en.wikipedia.org/wiki/Rock_Dove

1.5 chickens lays 1.5 eggs, thus 1 chicken lays 1 egg as there is a 1:1 correspondence.\n\n1 chicken lays 1 egg in 1.5 days, so 1:1.5 is .6:1, one chicken will lay .6 or 2/3 of an egg in one day.

It sounds like the robins nest was victimized by a mocking bird.  \n\nMocking birds will knock eggs out of nests in order to make it their own.  If the robin caught the mocking bird in the act there would have been an altercation.  \n\nIf a robin's eggs become under suspect in anyway, then the robin will abandon the eggs.\n\nIf you are able to get the egg to hatch taking care of a baby bird is a 60 minute an hour, 24 hour a day, 7 days a week project.  \n\nIf you have heated the egg to the point where it is "very hot" then the egg is most likely dead.  It should normally be just a little warmer than room temperature.  (About 85-90 degrees air temperature.)

Many bats also delay implantation after the eggs are fertilized.  There are also several mammal groups that have delayed fertilization, holding viable sperm for months until they are ready to begin gestation, and then an egg cell is fertilized.\n\nThis is possible in placental mammals where the egg cell is kept internal, and doesn't have a shell to protect it from the outside environment.  I doubt that it would be possible in, for example, birds, where once the egg is formed it's pretty much a done deal, and development goes ahead regardless of outside conditions.

The time it takes for a weaver bird to build a nest depents on the strength, agility, and skill of the birds.  All together, it will take a very long time for a weaver bird to build a nest because:\n\nThe nests last well through the 3-month breeding season, sometimes even up to a year. After the breeding season, other small birds may roost in the abandoned nests. The nests are made entirely out of strips of grass which the birds collect by cutting a notch in a tall grass, then stripping off a 30-60cm length.  \n\nNo stalks or entire grass blades are used. The birds then use their strong beaks to weave and knot the strips of grass. A newly-made nest is green with fresh grass and turns brown as the grass dries. A bird may make up to 500 trips to complete a nest. Madoc reports that a "male" nest he examined comprised 3,437 strips of grass 4-50 cm long.

1-2 days it depends on alot of factors like weather, colony size, ect.

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

Biologically speaking they lay eggs in spring because the increasing day length triggers the brain to release reproductive hormones. Those hormones cause the birds to mate, which of course leads to eggs.\n\nEvolutionarily birds lay eggs in spring because summer and autumn are the times of most abundant food: insects, fruit, nuts, mice and so forth. By laying eggs in spring the young birds start flying when there is the maximum  amount of food around. That way they have a few months to learn how to hunt, find berries and so on before it becomes difficult. By the time winter comes they have become proficient at finding food, so even though there is less food around in winter they have become so good at finding it they won’t starve. If eggs were laid in winter or autumn the young would be trying to learn how to find food when food is most scarce and they would almost certainly starve before they learned.\n\nThe abundance of food in spring and summer also make sit easier for the parents to find enough food to bring back to the nest.\n\nSome people will try to tell you that birds nest in spring because they can’t keep the eggs warm in winter. Of course this makes no sense because many penguins lay their eggs right at the very beginning of winter. They do that because the maximum amount of food available in the Antarctic occurs right at the very end of winter and start of spring. By laying their eggs at the beginning of winter the penguin chicks start swimming right when the maximum amount of food is available, just as other birds start flying just when the most food is around.

Only about 2 weeks.  A mating pair of robins might have two or three different "clutches" of eggs over a season, so they can raise two or three families a season.\n\nThese links should help you.

In order for an egg to hatch it must be fertilized.  Therefore, it takes two creatures to make a fertile egg.  For the chicken to predate the egg, there would have to be two chickens before the egg; a hen and a rooster.  Eggs are also often laid in batches.  Therefore it seems more likely that two creatures (not quite chickens) conspired to fertilize and lay a batch of eggs that became (male and female) chickens and when hatched they could have even more chickens.  This proves that the eggs were first.  A chicken is distinct from all other creatures because of its unique DNA and number of genes as received from two parents.  Only in the egg could the first correct set of DNA occur.  But I don't want to end an interesting argument.
