Concerned about stunted growth in chickens? Uncover the potential causes and effective solutions to promote healthy and robust development in your flock.
Stunted growth in chickens has increased over the past decade, causing farmers and breeders to struggle with improving their birds’ growth rates.
But why is this so? What is the causative factor for stunted growth in poultry?
This article discusses the causes of stunted growth in chickens and offers strategies to promote faster, healthier growth.
What is Stunted Growth in chickens?
Stunted growth is a condition in which the growth of a chicken is below the expected standard. Stunting can occur naturally, or many other factors could cause it.
Scientists from the UK have found a big problem affecting many chickens around the world. It is estimated to affect between 4.5% and 25% of all chickens.
Stunted chickens are smaller than their flock mates, have weak legs, and poor feathers, and are more likely to get sick.
How do you know your chickens have stunted growth?
You can know if your birds have stunted growth by measuring their body weight, body weight gain, or growth rate. The following illustration shows how we can determine if a bird has stunted growth.
A farmer raises a flock of broiler chickens for Easter. Each week, the farmer weighs the chicks and compares the weight to the previous week.
If the chickens weigh less than expected, the farmer can assume their growth is delayed, resulting in stunted growth.
What Causes Stunted Growth in Poultry?
According to experts, nutritional deficiency causes stunted growth, environmental factors, overcrowding, and a lot more. Let us have a look at some of these reasons.
Nutritional Deficiency
The chicken industry has been dealing with the stunting of growth in chickens for quite some time.
Scientists from the United Kingdom conducted a study and found a widespread problem affecting a considerable number of chickens globally. The issue is estimated to impact between 4.5% and 25% of all chickens.
A professor of animal nutrition at Auburn University has shown that inadequate energy and protein can lead to stunted growth in animals.
He says that there are different causes of stunted growth, but one of the major ones is nutritional deficiency. You can define nutritional deficiency as the lack of essential nutrients in an animal’s diet.
Phytate: An antinutrient
Poultry producers, chicken breeders, and feed mill operators use different feeding formulae to improve the quality of their chickens. These formulas include diets that contain wheat, maize, and soya beans.
Some of these formulas have been affecting the growth of their birds because of the high levels of phytate.
Phytate is a naturally occurring anti-nutrient found in many plant sources, including grains and legumes.
It prevents your chickens from absorbing nutrients and minerals by reducing the digestibility of these nutrients.
You want them to be healthy and grow quickly when you raise chickens. It is important to buy poultry feed from feed millers that produce good-quality feed without phytate.
A good feed mill that is worth its salt will add phytase, an enzyme, (Not phytate), to its produced feed to help chickens digest protein, phosphorus, and other nutrients in the feed.
Poor Chicks Brooding
If baby chicks don’t eat the right food after hatching, they can have a nutritional problem. The food that you give your baby chicks must contain all the nutrients they need to grow healthily.
Some farmers give their chicks too little protein, fat, and calcium. This will reduce the growth rate of the birds and can lead to stunted growth.
To increase the growth rate of your chickens, you need to feed them a diet that is rich in nutrients. This will make them grow faster and produce more eggs and meat.
Insufficient fresh water.
Make sure that your chickens have access to fresh water, especially during the growing phase.
Your chickens must have access to clean drinking water. Without access to clean water, chickens’ growth is hindered, increasing the chances of death.
Providing clean water to your poultry is crucial for digestion and nutrient absorption, which promotes healthy growth.
Change the drinking water regularly to keep your birds healthy. Dirty water can cause digestion problems.
Environmental Factors
Monitor the temperature because heat stress can cause stunted growth. Make sure that it is not too hot or too cold for your chickens.
If your area gets too warm, make sure that your chickens stay in the shade. Monitor the amount of humidity in your area. Make sure that there is enough humidity so that your chickens don’t get sick.
Overcrowding
There are several factors to consider when keeping poultry birds for maximum growth. Overcrowding can hurt the health and growth of your chickens. They will be less active and will eat less, so they will take longer to grow and lay eggs.
One of the most important things about chickens that grow well is that they require a lot of space.
To ensure the optimal growth and health of your chickens, provide them with sufficient space and proper ventilation.

Disease Outbreak
In the past few years, there has been an increase in the number of diseases that have affected chickens.
These diseases have resulted in a decrease in the production of chicken meat and reduced egg production because of stunted growth occasioned by the inability of the birds to combat infections and diseases.
Some of the diseases that cause stunted growth in chickens include
- coccidiosis
- fowl pox
- salmonella
Coccidiosis is a parasitic disease caused by protozoa called coccidia. This parasite lives in the intestinal tract of chickens.
Fowl pox is a viral disease that causes growth problems. Salmonella is a bacterium that can cause illness in birds and retard their growth.
To protect your flock from diseases, get healthy chickens, vaccinate them, keep the poultry pen clean, and follow strict biosecurity measures.
Conclusion
In conclusion, there are several reasons why chickens can’t grow as fast as they should. The first thing that you should do to avoid stunted growth is to feed your chickens a balanced diet.
They need to eat a wide range of foods. They need to be fed a diet that contains protein, carbohydrates, fats, vitamins, and minerals.
Make sure that the pen temperature is conducive for them. Your chickens must be in a healthy environment for them not to be susceptible to diseases and infections.
