Ducks show a strong appetite during the laying period, often gathering and competing for food, which indicates they are in good health and can be fed more. Monitoring their feeding behavior is crucial for maintaining productivity.
The shape of duck eggs can also provide clues about the ducks' health and feeding habits. Eggs that are more rounded suggest strong feeding and proper management. If the large end of the egg is small, it may indicate early feed deprivation, while a pointed small end could signal insufficient nutrition. In such cases, increasing feed quantity is recommended.
Eggshell quality is another important indicator. Thin, rough, or soft shells usually mean a lack of calcium in the diet. To address this, supplementing with bone meal or shell powder can help ensure balanced nutrition.
When eggs are heavy and large, it's a sign of good feeding. Typically, 14 eggs weigh around 1 kg. However, if ducks aren't getting enough water or feed, it may take 16 to 18 eggs to reach the same weight.
The timing of egg-laying is also a useful indicator. Ducks typically lay eggs between 2 a.m. and 5 a.m., which shows they are being fed properly. If laying time is delayed and egg size decreases, it’s time to improve the nutritional content of their feed.
Healthy ducks generally weigh between 1.4 to 1.5 kg. If their weight remains stable after a laying period, it suggests that the feeding regimen is well-balanced.
Feather condition reflects feed quality. Ducks with smooth, tight feathers are a sign of good nutrition, while loose or dull feathers may indicate poor feed quality and the need for improvement.
High-producing ducks should be lively and active. If they appear sluggish or unresponsive, it may be a sign of illness or weakness, and prompt attention is needed.
Feces analysis is also a valuable tool. If the feces are all white, it may indicate excessive feed intake and poor digestion. If the feces are loose but have less white matter, it suggests a balanced diet. However, yellow-white, gray-green, or bloody feces are signs of illness and require immediate treatment.
Lastly, observe the ducks’ behavior. If they panic when entering water, avoid bathing, have drooping wings, or move sluggishly, it could be a sign of illness. In such cases, quick action is necessary to prevent further health issues.
