Environmental conditions that cause mutualism: excessive stocking density, lack of space in poultry houses, excessive temperature during brooding, inadequate feeding and drinking, restricted feeding or starvation, high light intensity, and humidity. Feed pellets are more likely to cause mutual entropy than powders.
Nutritional factors that cause mutualism: lack of dietary protein, insufficient calcium and salt, excessive plant protein, especially soybean meal, insufficient animal protein, insufficient sulphur amino acids, microelements, and minerals, insufficient crude fiber, intrusion by external parasites, and sleepiness Eating mildew beverages causes dermatitis and delirium in chickens, and causes other chronic enteritis to cause poor nutrition absorption and mutual envy.
Other reasons: Native breeder chickens and egg breeders have a good temperament and are prone to squabbling; precocious hens are more neurotic and prone to spasm. The chicken can be effectively cut off or removed when it is timely cut off or removed.
