Prevention and treatment of panic disorder in laying hens with struggling wings and screaming nerves

Caged laying hens, especially light layers, tend to be neurotic. The nerves of this kind of laying hens are highly excitable. when stimulated by a certain factor, the chickens suddenly appear panic and riot, struggling desperately in the cage, flapping their wings and screaming one after another. As a result, some laying hens had broken wings, some had internal bleeding, some had premature unshelled eggs, and some died. The result of surprise is often a decline in the laying rate.

Laying hens

Neuroticism often occurs in laying hens at the age of 36 to 37 weeks, or at the peak of egg production. Laying hens raised on the Internet and on the ground are rare. Causes of neuroticism: sudden noise, flashing light, cut off water and materials, excessive density, breeders wearing strange clothes, birds passing by, airplanes flying, excessive magnesium content in feed, and so on.

Laying hens with panic attacks are very neurotic and prone to intermittent "frying" phenomenon. Hens stretch out their head and neck, their eyes are wide open, and they are highly nervous. If there is any movement, they will scream and fly randomly, affecting the whole henhouse. Sometimes, even if there is no obvious stimulating factor, there will be a phenomenon of panic. In addition to deaths and injuries, the laying rate of hens will also decrease, soft-shell eggs will appear, and the rate of broken eggs will increase significantly. For example, caged laying hens are in the peak period, and the laying rate reaches 88%. At more than three o'clock in the morning, there is a sudden "flock", the chickens are screaming and jumping around, and the chicken owners turn on the lights, water and feed want to calm the chickens down, but to no avail, the riot did not calm down until more than 8 o'clock in the morning. As a result, 10 laying hens broke their legs and wings, 2 died of viscera rupture, and 3 died of uterine prolapse. The laying rate of the flock will reach 32%, and it will only rise to 80% after 3 weeks. In another chicken farm, laying hens that got stuck and died of decapitation were always found in the cage in the morning. Man-made destruction or infectious disease? After the investigation, the reason is that several female breeders often wear bright clothes and change every day, and the chickens are in a state of panic. In the case of eager to run for his life, he stretched out his head, but could not escape and retreated violently, so he got stuck and died without a head. The above two examples show that under the condition of captivity, chicken neuroticism will bring heavy losses to the chicken farm. Therefore, it is important to keep a quiet environment, avoid abnormal sound, sudden flash, strangers or gorgeous costumes in the chicken flock, and prevent rats, cats and birds from entering the chicken coop.

Brown-shell laying hens are gentle in temperament and generally do not have much neuroticism. Chickens that often occur in flocks, adding 200 grams of nicotinic acid per ton of feed, can alleviate the occurrence of flocks.
