The eggs laid by the parrot on September 20 can't be applied now, and if he keeps applying them from the time he lays eggs on the 20th, he can put them on.
Birds. Birds are usually feathered, oviparous animals with a very high metabolic rate, and the long bones are mostly hollow, so most birds can fly. Birds evolved from reptiles, and there are more than 9,000 species of birds in the world, all of which have wings and feathers, even those that have lost the ability to fly (such as ostriches, penguins, etc.).
The first birds appeared 100 million years ago.
The body is spindle-shaped, the forelimbs are specialized into wings, the body surface has feathers, the body temperature is constant, the musculothoracic is developed, the bones are healed, thin, hollow, and the brain is relatively developed. Having an air bag allows for double breathing, and not having a bladder can reduce body mass. These physical traits are well adapted to flying.
Birds have no teeth but have beaks that can be used to hunt, build nests, and groom their feathers. Birds are good at building nests, and they can build all kinds of nests from the materials they collect. Ornithischia is taxonomically a class under the subphylum Vertebrates.
Feather. Birds are the only animals on earth that have feathers. The vast majority of a bird's body surface is covered with feathers, which not only keep the bird at a constant body temperature, but also allow it to fly. Birds have different shapes of feathers.
Structure. The ** of a feather has a hard shaft, called the feather shaft, the upper feather part is called the feather trunk, and the lower part inserted into the ** is called the feather root. The feather trunk is flanked by feathers, which are made up of a tough substance called keratin, which in turn is made up of feathers and branchlets.
Grow. Feathers are grown from the follicular vesicles of the feathers on birds**, and the parts are grouped together in a special way. Most birds moult at least once a year, when new feathers grow and old feathers fall off. Birds renew their already damaged feathers through moulting.
Freshman. Birds usually moult twice a year, which shows that feathers have a strong ability to regenerate. Scientific studies have shown that feather stem cells are distributed in a ring on the wall of the feather follicular vesicle, which can proliferate and differentiate, and the differentiated cells grow upwards to produce feathers.
The proliferation and differentiation of feather stem cells allows the entire feather organ of birds to grow and regenerate.
Type. Bird feathers can be broadly divided into four types: body feathers, down feathers, tail feathers, and wing feathers.
The body feathers cover the whole body, forming a smooth, streamlined body surface of birds; The down is fluffy, so that the warm air will not dissipate quickly; The tail feathers and wing feathers are more powerful and are used for flight.

Eggs can still hatch on September 20th.

Parrot eggs can hatch in about 20 days, in summer when the weather is hot and it may be about 18 days to hatch, and in winter when the weather is cold, it may take about 22 days to be hatched. After sexual maturity, parrots can be paired and reproduced, and after a successful pairing, they can produce eggs about a week later, and a nest can breed four to seven eggs, and after holding the nest, they can hatch small parrots.
Newly hatched parrots are fragile and immature, and need more care from their owners. You can feed them more foods that are high in nutrients, and you also need to pay attention to the time and amount of feeding. They need to be fed every two to three hours or so, but don't feed too much, too much will cause them to accumulate food, so eat small and frequent meals.
You also need to pay attention to keeping them warm to avoid them catching colds, which will affect their physical development. Their resistance is poor, so to ensure that the hygienic environment of the cage is clean and to avoid the growth of bacteria and cause them to get sick, the cage needs to be cleaned 2-3 times a week.

The incubation cycle of parrots is generally 19 days. If everything is in order, the little parrot will break out of its shell in about 20 days!
The female does not leave the nest after laying eggs until the end of hatching, during which time the male is fed with food. The incubation period is about 18 days. Budgerigar.
The chicks are late adults and cannot live independently within 25 days of hatching, so they rely on adult feeding. The method of brooding of brooding in parent birds is as follows: the male feeds the female, and the female feeds the chicks.
After 28 days of growth, the chicks are able to feed themselves and live independently. Sexual maturity can be reached in 5-6 months.
Also, we must pay attention to keeping the male birds active at a certain level, such as taking a cuttlefish bone for them to hold, and buying some cheap small toys for them to play with, which is not expensive and troublesome. So as not to let the idle male bird run into the nest to spoil the eggs, frighten the mother bird, and bite the chicks.

Parrot eggs hatch for 32 days and generally do not hatch.
The incubation cycle of parrots is generally 19 days. If everything is normal, the little parrot will break out of its shell in about 20 days.
In the breeding of pet birds, the breeding of parrots is considered simple. Limb fluids only require you to have a pair of healthy, young and mature birds, plus a nest box for breeding. Many people can easily reproduce with a mask.
Note that once the parrot eggs are safely placed in the incubator, precise temperature and humidity need to be maintained. Make sure the tray inside the incubator is filled with water, taking care not to starve the incubator of oxygen. The development of the embryo can be checked daily by candlelight.
When the embryo is developing smoothly, there are new changes every day.
