Why Chickens Laying Thin-shell Eggs and How to Prevent? T
here are many reasons for layer chicken producing thin-shell eggs, such as being scared, lack of calcium, poor ventilation in the house, and infrequent disinfection. We can solve this problem by adding calcium to the feed, ventilating the house, and regular disinfection.
soft-shell eggs. Therefore, to improve feed quality, increase animal protein feed, and often basking in the sun, strengthen feeding management, and promote laying hens to restore physiological functions as soon as possible, to ensure that the chickens can lay eggs normally. 2. Genetic factors
Physiological factors 1. Continuous egg production
Hens lay eggs continuously for a long period of time, which can easily lead to the decline of physiological functions, often making the eggshell thinner or producing
LIVESTOCK & POULTRY ME
Different breeds of chickens have different eggshell qualities, such as native eggshells with thicker shells, and exotic breeds with thinner shells that are easily broken. Therefore, the selection method can be used to increase the thickness of the eggshell of
the variety and reduce the egg breaking rate. 3. Egg-laying time
General chicken farms are fed around 8 am. During the day, the blood calcium concentration is high, and the calcium secretion of laying hens during egg formation is sufficient. Therefore, the egg shells produced in the afternoon are generally thick. Eggs laid before 10 a.m. are usually formed at night. Most hens are at rest at night. The food intake is very small and the blood calcium concentration is low. Therefore, eggs laid in the morning are generally thin.
