Chicken contact lenses are indeed a real thing, and companies like Animalens Inc. have been manufacturing them for quite some time. The idea behind these lenses is to reduce stress and aggressive behaviour in chickens, thereby increasing egg production and reducing cannibalism, a distortion of their natural behaviour caused by modern housing. These lenses are designed to stay in place for about a year, after which they need to be replaced. While some farmers were initially sceptical, others agreed to trials, and the lenses are now being used on hundreds of thousands of chickens nationwide.

What You'll Learn
Animalens Inc
The lenses are designed to reduce stress in the chickens' lives and make them more productive. Studies have shown that chickens wearing the lenses eat less, produce more eggs, and fight less with other chickens. The lenses can be put in place in seconds and stay in place for the life of the bird, or about a year. They are priced at a modest 20 cents a pair, or 15 cents if bought in bulk.
The technology behind the lenses is quite intricate. Early lenses blinded the chickens, so the lenses had to be carefully designed to not distort the chickens' vision or irritate their eyes. The lenses are made of non-gas permeable moulded material, which does not allow the eye to breathe or receive oxygen. This can lead to corneal ulceration and increased risk of microbial contamination, so it is important to properly care for the lenses.
With the potential benefits of reduced cannibalism and improved egg production, Animalens Inc. believes that their product will be a success and that farmers will soon flock to buy their lenses. The company aspires to expand globally and capture a significant portion of the chicken contact lens market.

Chickens become less aggressive
Aggressive chicken behaviour, although it may sound amusing, can be dangerous. Aggression in chickens can be caused by a variety of factors, including genetics, hormones, instincts, and behavioural reinforcement. Roosters, for instance, are more likely to be violent and use their spurs and beaks to draw blood.
There are several methods to reduce aggression in chickens. Firstly, it is important to establish dominance and position oneself at the top of the pecking order. One way to do this is by grabbing the bird by the feet, turning it upside down, tucking it under your arm, and holding it until it acknowledges your dominance. Another method is to wear protective gear and not back down when a chicken attacks, as chickens can perceive humans as threats and attempt to establish dominance.
Additionally, ensuring that chickens have access to adequate food and water can help reduce aggression, as competition for resources can lead to weight loss and weaken birds, making them vulnerable to aggression from the flock. Providing an enriching environment and maintaining a consistent routine can also help, as chickens are active foragers and changes in their daily schedule can be stressors.
Furthermore, maintaining a flock size of either small or large, rather than an intermediate size, can reduce aggression. In larger flocks, there is less recognition of members, leading to a less rigid hierarchy and increased tolerance. Introducing new birds to the flock gradually and keeping them separated initially can also help reduce aggression.
Interestingly, the use of rose-tinted contact lenses or eyeglasses has been proposed to reduce aggression in chickens. The idea is that the red colour prevents chickens from recognizing blood, which may otherwise trigger injurious behaviour. While some companies have marketed such products, there is skepticism about their effectiveness, and early attempts at chicken lenses blinded the chickens.

Farmers' scepticism
While some farmers were intrigued by the potential benefits of chicken contact lenses, others were initially sceptical of the idea. Some farmers thought Randy, the founder of Animalens Inc., was a con man trying to steal their money. They had doubts about lens installation and whether the lenses would work on all breeds of chicken. They also wanted to try a free trial before investing, which Randy refused.
Indeed, the technology for chicken contact lenses did not always exist. The elder Wise, Randy's father, had tried to produce lenses for chickens in the early 1960s, but the early lenses blinded the chickens, and his company folded. It was only later that Randy Wise was able to design lenses that would not distort the chickens' vision or irritate their eyes.
Even with the improved technology, some farmers remained sceptical. One farmer installed red lights inside his chicken farm, achieving the same result as the contact lenses without having to install them on individual chickens. In addition, some people believed that the purported blood-masking effect of the rose-tinted lenses was a myth, as chickens are colour blind.
Despite the scepticism, Wise's company, Animalens Inc., has grown. The lenses are already on 100,000 chickens nationwide, and Wise is confident that farmers will soon flock to buy his contact lenses. With 1.2 billion laying chickens in the US, the potential savings for farmers could be $600 million. The lenses can be put in place in seconds and last for about a year. They have been shown to reduce aggression and increase egg production in chickens.

Design challenges
Designing contact lenses for chickens poses several challenges. Firstly, the lenses must be carefully designed to ensure they do not distort the chickens' vision or irritate their eyes. This was a significant obstacle for Wise, the founder of Animalens Inc., who kept a jar of hundreds of failed test lenses in his office as a reminder of the trial-and-error process.
Another challenge is to create lenses that are durable and long-lasting. The lenses are designed to stay in place for the life of the bird, which is typically about a year. This means the lenses must be able to withstand the rigours of a chicken's daily activities without dislodging or becoming damaged.
Additionally, there is the challenge of scaling the production of the lenses. With approximately 250 million chickens in the USA alone, the potential market for chicken contact lenses is vast. However, producing enough lenses to meet demand while maintaining quality control standards presents a significant logistical hurdle.
Furthermore, there are biological challenges to consider. Chickens have complexly sensitive beaks and eyes that are adaptively correlated for foraging and other activities. Ensuring that the lenses do not interfere with these natural behaviours requires a deep understanding of chicken physiology and behaviour.
Lastly, there is the challenge of consumer acceptance. Some farmers may be sceptical of the product or concerned about the installation process. Gaining their trust and confidence in the effectiveness of the lenses is crucial for the widespread adoption of chicken contact lenses.

Cannibalism in chickens
Cannibalism in poultry is defined as the act of an individual of a poultry species consuming all or part of another individual of the same species as food. It is a costly habit that poultry producers cannot afford to ignore, as it can cause large mortality rates within the flock and large decreases in production due to the stress it causes. Cannibalism in poultry is influenced by various factors, and understanding these factors is crucial for implementing effective prevention and treatment measures.
One significant factor contributing to cannibalism in chickens is flock size and social hierarchy. Intermediate flock sizes can lead to confusion and higher aggression as different birds attempt to establish dominance. In contrast, very large flocks may prevent the recognition of a dominant bird, disrupting the social hierarchy. Additionally, when crowds are too close together, dominant birds fight more often to maintain their position, increasing the risk of cannibalism. Flock owners should be careful to maintain appropriate distances between birds to reduce aggression and the subsequent risk of cannibalism.
Lighting and temperature conditions also play a role in cannibalism. Prolonged exposure to high-intensity light and overheating can increase stress and discomfort in captive poultry, leading to aggressive behaviours and cannibalism. Similarly, exposing birds to extremely bright light or excessively long periods of light can make them hostile towards one another. Therefore, it is essential to provide adequate lighting conditions and maintain optimal temperatures to prevent cannibalism.
Nutrition is another critical factor influencing cannibalism in chickens. A diet lacking sufficient protein can lead to aggressive behaviours as chickens, especially laying hens, seek alternative protein sources. Feathers are rich in keratin, a type of protein, and can become a target for pecking, leading to cannibalism. Young chicks may also take pin feathers from other chicks to meet their higher protein requirements during growth. Therefore, ensuring adequate protein levels in the diet is essential for reducing cannibalistic tendencies.
Injury and blood are also significant triggers for cannibalism in chickens. Once a bird is wounded, the sight of blood can lead to relentless pecking by other birds. This behaviour may be driven by a redirected foraging or feeding instinct. As a result, it is crucial to address injuries promptly and divert attention away from wounded birds to prevent cannibalism from occurring.
While the idea of cannibalism in chickens may be disturbing, it is important to recognize that chickens are reacting to opportunities and stimuli in their environment. By understanding and addressing the factors that contribute to cannibalism, poultry producers can implement effective management strategies, such as crowd size control, beak trimming, light manipulation, and nutritional adjustments, to successfully prevent and control cannibalism within their flocks.
