Common hatching problems in chickens
In the hatching process, there are often some problems, such as: the egg is a white egg, the white dot-shaped blastoderm is visible in the necropsy; there is no blood ring, no fertilization, etc. The main reason is that the cock has not reached sexual maturity.
The rooster should be stimulated by light two weeks earlier than the hen. The rooster's morphological abnormalities and the hen's follicle (blood blast) are abnormal. This often happens when the bird is too young or too old, or it is a male or a female. Unreasonable quantity distribution, too few cocks, resulting in insufficient mating frequency; too many cocks, leading to roost and fighting. The reasonable ratio of male to female should be: light chicken 1:12-15, heavy chicken 1:10-12.
The direct reasons for the decline in fertilization rates, such as: extreme weather conditions, aging flock, diseased flocks, can often be manifested by rough, distorted eggs or shell eggs; excess body weight, especially for meat breeders (> 4,800 grams, 10.6 pounds); Nutritional deficiencies or excesses; Overfeeding restrictions; Leg and legs disease, especially heavy cocks; Certain drugs: such as pesticides, chemicals, toxins, mycotoxins, etc.; Parasites, such as certain protozoa The breeding density is too large; the mating frequency decreases or does not mate.
