What kind of bird can only lay eggs and not hatch eggs?

Cuckoo! The most well-known trait of this bird is the hatching parasitic nature. This characteristic is found in all species of the Rhododendron subfamily and in the three species of the subfamily Terranidae, i.e. eggs are laid in the nests of some species of birds, where they are incubated and brooded by adoptive parents.

The 47 species of the Rhododendron subfamily have different adaptations to increase the survival rate of young chicks, such as the eggs of the cuckoo resemble the eggs of the host (mimicry), thus reducing the chance of the host abandoning them; Cuckoo adults will remove one or more eggs from the host so that the host will not see the increase in the number of eggs, which in turn reduces the competition of the host chicks. Cuckoo chicks push the eggs and chicks of their nesting hosts out of the nest. Some cuckoos resemble accipiters in appearance and behavior, and are frightened by the host, so they can approach the host's nest undisturbed. The non-parasitic cuckoo is represented in North America by the widespread yellow-billed cuckoo (Coccyzus americanus) and the black-billed cuckoo (C.).

erythropthalmus)。Little American cuckoo (cminor) is found in the United States on the southern coast of Florida, but also in the West Indies, Mexico, and northern South America.

There are also 12 species of non-parasitic ground cuckoos in Central and South America, some belonging to the genera Saurothera and Piaya. There are 13 species of cuckoos in the Eastern Hemisphere, divided into 9 genera. Ground cuckoos nest in low vegetation with tree branches.

Both females and males participate in egg holding and brooding.

It is estimated that only the cuckoo bird does this kind of thing, and the cuckoo bird always lays its eggs in the nests of other birds, and does not care about anything itself.

Domestic ducks do not hatch eggs, and cuckoo birds do not hatch eggs because of artificial culture.

The cuckoo bird, which lays eggs on the nests of other birds, allows it to incubate and raise the eggs for itself.

No. Egg hatching is when birds keep the eggs at the right temperature so that the young can develop inside the eggs. Most birds, such as puffins, sit on top of their eggs and incubate them.

But the Sula mound pheasant has a different approach. It covers the eggs with plants and sand, and uses the heat released by the plants as they decay to help it hatch the eggs.

In some birds, the female is responsible for foraging and replenishing energy during the incubation period, such as the hornbill that builds a hole in the trunk of a tree. House swallows, swans, cranes and other birds, male and female parent birds take turns to take the task of incubating eggs; Polyandry birds such as pheasants and painted sandpipers have a more unique way of incubating eggs, and the male bird completes the egg-incubation alone.

There are many ways to incubate eggs:

During the incubation period of the mother and father birds, there are several ways to incubate the eggs of both parents, single parents to incubate the eggs and group to incubate the eggs.

There are exceptions, the largest emperor penguin in the penguin family, although they are also monogamous during the breeding season, but the eggs are hatched by the penguin father. Daddy Penguin wrapped his eggs tightly in a bag full of blood vessels under his abdomen, keeping the egg temperature at around 36, withstanding the cold of Antarctica. For more than 60 days, the father penguin did not eat or drink, and only relied on the fat stored in his body to maintain his physical fitness until the baby penguin broke out of the shell.

There are many ways to hatch bird eggs, such as ondol incubation, hot water tank incubation, and machine incubation. Either way, it relies on controlling the temperature to allow the chicks to break out of the shell smoothly. If you want to make your own incubator, you can prepare a shoebox with some soft clothes in it, or spread it with feathers, and also put a glass of water to keep the environment moist, put the eggs in it, and turn it several times a day.

Methods of artificial incubation of bird eggs:1First of all, we need to prepare the eggs of the conceived bird and put them in the hatching tray.

2.Next, the eggs are placed in an incubator with a temperature control of about 70% and a humidity of about 70% to 80%. The birds will hatch in about 20 days.

3.During the incubation period, be careful to remove the hatched birds and avoid breaking the remaining eggs. 4.

The temperature should be strictly controlled during incubation. After a while, the fluffy bird hatches.

I've noticed dark shadows and bloodshot now.

Take your flashlight and shine a light on the eggs to see if they are fertilized eggs. There's not a little bit of it in it.

It is to continue to hatch as I ask.

Yes, I can already see the form of a bird.

I've bought the kind of incubator that turns eggs automatically, why does the egg head face downwards?

I jumped at a temperature of 60 to 85 humidity

This is not related during development. You can adjust the temperature and humidity as well.

The incubation methods of bird eggs include: natural incubation, water tank incubation, electric blanket incubation, etc.

1. Natural incubation.

When using the natural method of hatching eggs, it is necessary to choose a small size, a strong nest of hens to incubate, in the early stage of incubation, when the hens leave the nest to eat, to prevent the hens from stepping on the eggs, if the temperature is low, should be covered with cotton blankets on the nest for insulation, generally 30-40 pieces can be hatched each time.

2. Water tank incubation.

Bird eggs can also be hatched in a water tank, prepare a water tank of the same caliber before hatching, an aluminum plate and a quilt for heat preservation, etc., put 30-40 eggs into a small mesh bag, and then put it into the aluminum tray, wrap the water tank with cotton wool to keep warm, access 50-70 warm water, and finally put the aluminum plate on the water tank, and then cover the quilt.

3. Electric blanket incubation.

Spread a layer of cotton wool under the electric blanket, cover a layer of cotton blanket, lay a few square wooden sticks of 3-5 cm on top, put the egg tray on the square wood, stack 2-3 layers, then cover the quilt, and turn on the electricity to heat, turn the eggs 5-6 times a day during incubation, and check the temperature every 30 minutes.

Precautions for dressing bird eggs

1. Eggs should be left standing for 2 to 3 hours.

Many netizens can't wait to hatch after buying fertilized eggs from the Internet, but they don't know that after a long journey, the eggs are shaken and the size of the air chamber is changed in the process of transportation.

2. Don't flip eggs at will.

Do not turn the eggs for the first three days of incubation, and stop turning the eggs after 15 days. You can use a marker pen to mark the eggs, and you can clearly know which ones have been turned and which ones have not been turned when turning the eggs. In order to avoid uneven egg turning and stunting.

Generally, it is turned once in the morning and once in the evening, at least 2 times a day.

3. Shine on the eggs. When incubating in winter, we must pay attention to the temperature, cold in winter, the whole incubation process only needs to shine the egg 2 times, too many eggs are easy to cause flash eggs, resulting in stillbirth of eggs. The first time the eggs are incubated for 5-7 days, and if there are cobweb-like blood streaks inside, they can continue to hatch.

If not, it is azoospermic or weak sperm and needs to be removed, otherwise it will affect other eggs in the later stage and cause bacterial infection.

Eggs hatch in 15 to 21 days. The natural incubation time of bird eggs is generally about 15 days, while the artificial incubation time is about 21 days. However, the incubation cycle of bird eggs will also be affected by the temperature season and temperature of annual reproduction, and the warm season and suitable temperature are more conducive to the breeding of small birds.

Precautions for hatching birds' eggsMove the eggs in the air-conditioned egg storage to 22 to 25 degrees Celsius.

The indoor preheating for 6 to 8 hours, remove the moisture on the egg surface, and wait for the egg surface temperature to reach room temperature, that is, the yard disc is incubated, the first egg must be high-quality and disease-free, and then observe the surface of the egg, a good egg should be the shell thickness and uniform color is not damaged.

When tested with a lamp, the yolk fluidity of the large egg with bubbles and deformity can not be included in the selection of the final egg, the initial egg production is very dirty, there may be a large number of bacteria on the surface of the eggshell, so before the egg hatches, it must be disinfected, generally with ultraviolet radiation.

material paper.

raid box and a heat-generating light bulb.

1. Prepare a dozen fertilized eggs, a cardboard box and a heat-generating light bulb.

2. Put in an appropriate amount of sawdust and spread the sawdust flat.

3. Put the prepared eggs evenly into the carton.

4. Put a bowl of water in the corner of the carton to keep the carton moist.

5. Power on the bulb to provide temperature for egg incubation.

6. Seal the carton and put it in a quiet place.

Simple, look at whose budgie is it, the bird lays eggs, and the eggs will naturally hatch when you put them in its nest.

I can let birds that are incubating eggs such as pearl birds and seven sisters incubate, and I tried to hatch the eggs of colorful birds with seven sisters, and it worked!!

。。。You should go to the mother bird to incubate, or maybe the eggs can hatch as long as the temperature is kept all the time.

If you understand the technology, it's very easy to hatch eggs, I have my own hatching box in the space, and if you don't understand it, you can add me, first.

version, put in the hen's and duck's nest at night.

Right, because they will be pecked during the day, of course, if it is a small bird egg, because it is too small, it will be put in vain, because it will be broken, second, find a local hatchery, generally 1 to 2 yuan an egg, if it is not hatched, do not have to pay money, third, water temperature method, you have no way to this, no technology, fourth, electric blanket method, fourth, light bulb incubation, these are to control the temperature and humidity, so it is not recommended that you try,
