The main component and shape of foam: polymer, and it contains a large amount of foam. However, unlike plastic, foam is very light, so individual foam beads are easily crushed and deformed.
If you have used foam boxes at home, throw them away. When chickens find them, they will surround them. After a day or two, the foam box will be eaten by the chickens. It seems that the chickens really enjoy eating these foam boxes. So, why do they like it?
Chickens have diverse eating habits and are willing to try new things
First, let’s understand the natural feeding habits of chickens. Chickens are omnivores and consume a variety of food sources, including rice, insects, fruits, wheat, and corn, among others.

Why Do Chickens Like to Eat Foam? Uncovering the Truth Behind This Strange Habit
However, foam has a very different appearance and scent compared to these natural foods. It is made from polymers and has a smooth, lightweight surface. To chickens, these characteristics make foam seem like a special treat. A chicken may have never seen foam before, but when it detects the faint scent, its first instinct is to peck at it.
Surprisingly, when they take their first peck, they discover that foam tastes even better than grain. The flavor and texture of the foam are more appealing to chickens because it is light and easy to peck at.
While foam does not provide the nutrition that chickens need, and neither does it contain any harmful substances, it offers them a unique and enjoyable sensory experience, encouraging them to explore this novel food.
When chickens eat, their sense of smell becomes less acute, and they rely more on taste to determine if something is edible or not.
Chickens have small beaks and an even smaller sense of smell
You might not even notice a chicken’s nose without looking closely. All you’ll see is their long beak.
This is also due to their continuous evolution as social animals that need to compete for food quickly. If a chicken comes across something that looks edible, it will first try it with its beak, and ultimately, if it tastes good, the chicken will swallow it. If not, it will spit it out.
In other words, if a chicken sees something that might be edible and first smells it with its nose, there is a good chance that another chicken will snatch it away before it gets a chance to taste it.
So, while foam has a faint scent, a chicken’s sense of smell is not sensitive enough to detect any abnormality between the foam and regular food. Moreover, since chickens have been eating rice, millet, and corn for a long time, these foods look similar to foam, and thus, foam tastes great to them. At this point, there is no reason for a chicken to refuse foam.
Are there any negative consequences of chickens eating foam?
Chickens are unaware that foam provides no nutritional value, and they do not understand the potential harm it can cause. While foam may be appealing to chickens in some ways, consuming it over an extended period can be detrimental to their health.

Foam is made from polymers or other harmful materials, and if chickens ingest too much, it can lead to digestive issues, poisoning, or other problems.
Eating a small amount of foam will not affect chickens since they also consume sand and hard seeds, which help grind up the foam. Additionally, their stomach acids break down and eventually expel the foam from their bodies.
However, consuming large quantities of foam can be dangerous and even fatal for chickens. The stomach acids break down the foam, and if a large amount of residue is unable to be expelled from the body in time, it can put the chicken in a life-threatening situation.
Therefore, if you observe your chickens eating foam, the best course of action is to prevent access to it and provide them with a healthy, balanced diet to ensure their well-being.
