Ducks show a strong appetite during the laying period, often gathering and competing for food, which indicates they are hungry and can be fed more. Monitoring their feeding behavior is essential to ensure they receive adequate nutrition.
The shape of the eggs can also provide useful clues. Eggs that are more rounded suggest good feeding habits and proper management. If the large end of the egg is small, it may indicate early feed deficiency. If the small end is pointed, it could mean insufficient feed, so increasing the amount of feed is recommended.
Thin, rough, or soft eggshells are signs of calcium deficiency in the diet. To address this, it's important to supplement the feed with bone meal, shell powder, or other mineral sources to ensure balanced nutrition.
When eggs are heavy and round, they tend to be larger. On average, 14 eggs weigh about 1 kg. However, if the ducks aren’t getting enough water or feed, it may take 16 to 18 eggs to reach the same weight.
Observing the time when ducks lay eggs is also helpful. Ducks typically lay eggs between 2 a.m. and 5 a.m., which suggests they are being fed properly. If egg-laying is delayed and the eggs become smaller, it’s a sign that nutritional levels need to be increased.
Healthy ducks usually weigh between 1.4 to 1.5 kg. If their weight remains stable after a laying period, it shows that the feeding regimen is appropriate.
The condition of the feathers is another indicator. Ducks with smooth, close, and shiny feathers generally have access to high-quality feed. If the feathers appear loose or dull, it may signal poor feed quality, and improvements should be made as soon as possible.
High-yielding ducks are usually active, alert, and responsive. If they appear sluggish, uninterested, or unresponsive, it could be a sign of weakness or illness.
Examining the feces is also an effective way to assess health. If the droppings are all white, it may indicate overfeeding and poor digestion. If the feces are loose with less white matter, it suggests a balanced diet. However, if the droppings are yellow-white, gray-green, or contain blood, it may point to illness and requires immediate attention.
Finally, observing duck behavior is key. If ducks panic when splashing into water, avoid bathing, have drooping wings, or move weakly, it could be a sign of illness. These symptoms should not be ignored, and prompt treatment is necessary.
