How many times a year does a hen hold a nest, why does a hen hold a nest

<> the number of nest holdings of a hen is usually 1-3 times a year, and the nesting ability of native chickens is generally stronger than that of caged chickens. The hen's nesting time is generally from March to April, and each nest will last for about 20 days, during which its ovaries and fallopian tubes will degenerate, and its appetite and egg production will decrease. If you want to promote the hen to hold the nest, you can feed it for 3 consecutive days, the dosage is 2 tablets a day, and the nest can be held on the 4th day.

1. A hen holds a nest several times a year

1. The number of times the nest is held.

1) Under normal circumstances, hens can hold their nests 1-3 times a year, and the nesting ability of native chickens is usually stronger than that of caged chickens.

2) The hen usually begins to hold the nest in March and April every year, and each nest will last for about 20-40 days, during which its appetite and egg production will be reduced, and the ovaries and oviducts will also degenerate.

2. Nest holding skills.

1) Feed the hens with lactation tablets, 2 tablets a day, for 3 days, and on the 4th day, they will hold the nest.

2) Put some cotton wool and other warm materials in the chicken nest to enhance the warmth and promote the hen to hold the nest.

3) If the hen has the nature of holding the nest, the brightness of the nest can be reduced, the number of feeding can be reduced, and the eggs need to be avoided during the period.

4) Drive the hen into the chicken nest with 1 lead egg, and then cover 1 breathable bamboo basket, and then transfer it to a cool and ventilated position, in addition to feeding, feeding water, the rest of the time can not let the hen go out, so that after about 2-3 days can hold the nest.

2. Why do hens hold their nests?

1. Physiological reasons.

1) Hens have the instinct to reproduce, and some breeds are born with nest hugging behavior.

2) When the prolactin secreted by the anterior pituitary gland of a hen increases, its ovaries shrink, causing the nest to be held.

2. Environmental reasons.

1) When there is a large amount of eggs in the nest, it will induce the hen's nest holding behavior.

2) In late spring or summer, when the temperature rises slowly, the hen will hold the nest after the egg production increases.

3) In the case of cold weather, dim light, and narrow chicken nests, hens are prone to hugging their nests due to fright.

4) When there is a rooster around the free-range hen, it is also easy to induce the phenomenon of holding the nest.

Hens generally hold their nests 1-3 times, and the nesting ability of native chickens is usually stronger than that of caged chickens. When the prolactin secreted by the anterior pituitary gland increases, the ovaries shrink and the nesting phenomenon occurs. Nests are also affected by environmental conditions, and generally occur in late spring or summer when the ambient temperature gradually rises and the egg production is high.

During the hen nest period, due to the loss of appetite and physical energy consumption, the egg production will stop, so the hen nest will have a relatively large impact on the egg production.

The hen holds a maximum of a few eggs in the nest

1. It is generally better to put up to 15 eggs in the hen nest, and the specific number of eggs is related to the breed of the hen. Choose a hen with strong hugging, docile temperament, moderate individual size, and no ectoparasites as a nest chicken, put a few ordinary eggs before holding the nest and let the nest hen try to hatch for 2-3 days, if the hen squatting nest is better, you can officially put the egg for incubation.

2. The nest can be held with wooden boxes, cartons, baskets, etc., and the nest is covered with dry, soft and warm bedding, and the bottom of the nest should be flat, so that it is convenient for the hens to squat and turn the eggs. The nest should be placed in a quiet environment, air circulation, and dark light, and attention should be paid to preventing cats and mice from invading the nesting hens.

3. Feed the nest chicken with water and feed 1 time a day, feed with whole corn or wheat, and feed some green fodder appropriately. Some hens are reluctant to leave the nest, so they should be forced to catch them at this time, let them eat, drink and feces outdoors, and release them for about 20 minutes.

4. On the 7th and 18th days of the incubation period, the eggs should be illuminated once each with an egg illuminator to remove the infertile eggs and dead embryo eggs. If you find an egg in the nest that has been contaminated with faeces or has been trampled on, remove it immediately, wash the contaminated egg and put it back.

It is not based on the number of eggs.

Hen nesting is also called nest love, that is, the nesting nature of hens. It is a reproductive instinct of the hen. When the hen lays a nest of eggs, due to the increase in the lactation hormone secreted by the anterior pituitary gland, the various parts of the chicken body undergo great changes, such as the decline of ovarian function, the acceleration of blood flow in the body, the increase in body temperature, etc., so that the hen's neck and back feathers are erected, and the wings are opened, that is, the nest appears.

The hen holds the nest for a few days or several months, depending on the breed.

Causes of hen nesting.

1. Physiological factors.

In many places, chicken breeds and broiler breeders bred on this basis have a considerable degree of nest-hugging behavior, which is an instinct of poultry reproduction. The hen's nest is controlled by physiological endocrine, and when the prolactin secreted by the anterior pituitary gland increases, the ovaries shrink and the nesting phenomenon occurs.

2. Environmental factors.

Hen nesting is also affected by environmental conditions. Generally, in late spring or summer when the ambient temperature gradually rises and the egg production is large; Storing too many eggs in the nest can induce hens to hold the nest; In the free-range state, hens with rooster flocks are more serious in their nests.

Hens are usually nested in the early morning and late afternoon.

The hens hold their nests mainly because of the cold weather, the temperature drops, and the chicken nest environment is narrow and dimly lit. There are many reasons why hens are frightened and hold their nests.

Solutions to hen nesting:

1. The nest for incubating eggs should be spacious, and it is best to choose the hatching nest of the hen herself. You can also find a spacious utensil to turn the bedding in the chicken nest and put the eggs in. It is best to move the hen at night, with light movements, quiet environment, and low light. Don't frighten the hens.

2. Put enough corn kernels next to the nest to tease the collapsed amount. (This food provides high calories, is easy to eat, digests slowly, and supports incubation for a long time).

3. Put enough water, and the round groove of the water mountain should be slightly heavier, so as not to be easily knocked over by the light cherry blossoms. When the hen is hungry, it will come out to eat and drink on its own, and it can be fed if it is not needed, which will affect the mood of the egg.

4. After the chick comes out of the shell, it can be put into millet or feed with a heavier, shorter and large food tray, and the hen will guide the chick to eat, 2 days later, the hen will take the chick to forage everywhere, only provide food, and the manual does not need to be too involved.

1. Catch up and wake up the hug method: put the nest hen in the sports field, keep chasing, do not let it rest, there is no chance to lie on its stomach, so that it wakes up.

2. Water prison awakening method: put the nest hen in the basin with a cage, and then add water to it, the water depth to the chicken tibia can be, artificially caused so that the chicken can only stand, can not squat down the restriction conditions, so that the chicken will soon wake up. 3.

Hanging cage awakening package method: put the hen holding the nest into the cage, and then hang the chicken cage, so that the chicken will keep moving, the cage will be wobbly, and the chicken can not lie on his stomach in the cage, so that the chicken will wake up. 4.

Hanging and waking method: Tie one leg of the chicken with a rope, and then hang it up so that one leg hits the ground, creating a condition that cannot lie on the nest and prompt the chicken to wake up and hug.
