Hens typically start laying eggs after being raised for about 4.5 months. However, their egg production rate begins to decline after more than a year and eventually stops altogether. In Singapore, experts have conducted long-term experiments showing that an artificial method can extend the laying period of hens significantly. This technique involves temporarily stopping feed and water when the hens' laying rate drops, causing them to feel hungry and thirsty. After three days, they are given small amounts of water in the morning and afternoon for one hour, and on the fifth day, they receive 5 grams of feed, increasing by 5 grams each subsequent day. At the same time, the lights in the shed are turned off at night. Following this process, the hens molt and grow new feathers. By the 20th day, they enter a second puberty, and their egg production returns to its original level.
In Japan, some chicken farms have found that feeding fresh celery to hens can boost egg production by 15% to 20%. The recommended method is to feed celery three times a week, with about 50 grams per session. This includes both the leaves and chopped stems added to their regular feed. Additionally, 1 kilogram of celery can be mixed with 1.7 kilograms of boiled water and left to steep for about 15 minutes before feeding. This practice not only improves egg output but also enhances the overall health of the hens. Farmers who have implemented these techniques report better productivity and longer-lasting egg-laying cycles, making these methods valuable tools for modern poultry farming.
