Bald spots are a common occurrence in chickens and can be caused by moulting, feather pecking, or feather picking. Moulting is a natural process that occurs annually, usually in early autumn, where chickens lose their old feathers and grow new ones. Feather pecking is a form of bullying within the flock, where one chicken pecks at another, causing feather loss. Feather picking, on the other hand, is when a chicken pulls out its own feathers due to discomfort or stress. While moulting is a normal part of a chicken's life cycle, feather pecking and picking can be concerning and may require intervention to ensure the well-being of the flock.

What You'll Learn

Moulting
Some chickens experience a gradual moult, replacing feathers progressively from head to tail, while others undergo a 'total feather-drop' and lose most of their feathers at once, which can be alarming to witness. During moulting, chickens may appear withdrawn and paler in the face, comb, and wattles. They will also likely stop laying eggs as feather regrowth consumes all available nutrients. Therefore, it is essential to provide extra care, high-quality nutrition, and supplementation during this time.
To support moulting chickens and promote feather regrowth, nutritional supplementation with Biotin and other essential vitamins is recommended. Additionally, providing dust boxes with materials like diatomaceous earth or kaolin clay can help control ectoparasites like mites, lice, and fleas.

Feather pecking
Bald spots on chicks can be caused by moulting or feather pecking. Moulting is a natural process that occurs shortly after a chicken hatches, and they will have two or three moults before they achieve their adult plumage. This can cause the chicken to look withdrawn, and they will likely stop laying eggs as feather regrowth will take precedence.
In the case of the chicken mentioned in the search results with a bald spot on her head, it is suggested that another chicken is pecking at the back of her head to establish the pecking order. This is a common place for chickens to peck, and the feathers will likely grow back after moulting.
Genetics play a role in feather pecking, with light breeds more prone to the behaviour than heavier breeds. Chickens with muff feathers, beard feathers, or crest feathers may also be more likely to be targeted.
Dietary deficiencies, particularly of protein, sodium, phosphorus, or the amino acid methionine, can also cause feather pecking. High-energy, low-fibre diets can increase the activity and aggressiveness of the flock. It is important to provide a diet appropriate for the birds' current stage of growth.
Environmental factors, such as overcrowding, inadequate ventilation, and high temperatures, can also contribute to feather pecking. Overcrowding increases competition for resources and can lead to stress, which may trigger feather pecking. Additionally, chickens that are confined and unable to engage in natural foraging behaviours may redirect their pecking towards other members of the flock.
To prevent and address feather pecking, it is crucial to provide adequate space, improve ventilation, and ensure access to cool, fresh water. Dietary adjustments should be made to address any deficiencies, and it is important to provide a diet suitable for the birds' growth stage. Distractions, such as hanging treats or fresh greens, can help keep chickens occupied and reduce boredom, which is another potential trigger for feather pecking. In some cases, anti-pecking sprays may be necessary to deter chickens from pecking their flockmates. However, finding the right spray may require some trial and error.

Lice or mites
Bald spots on chicks can be caused by moulting or feather pecking. Moulting is a natural process in which a chicken loses its feathers and replaces them with new ones. Chickens moult shortly after they hatch and will have two to three moults before they reach adulthood. Thereafter, they will moult once a year, usually in early autumn.
However, bald spots can also be caused by feather pecking, which may be done by another chicken or the chick itself. Feather pecking by another chicken is usually done to assert dominance and establish the pecking order. Self-feather pecking, on the other hand, may be a sign of discomfort or stress.
While less common, bald spots in chicks can also be caused by lice or mites. These ectoparasites are typically carried by birds, rodents, and other wildlife, and can infest both the chicken and its coop. Lice and mites feed on the feathers, dead tissue, and blood of the host, leading to feather loss and bald spots. Other signs of a lice or mite infestation include dirty-looking feathers, decreased activity, pale combs, changes in appetite, weight loss, redness or scabs on the skin, and dull, ragged-looking feathers.
To prevent and treat lice or mite infestations, it is important to maintain good hygiene by regularly cleaning the coop and disposing of loose feathers that can carry hatching eggs (nits). In addition, limiting visits from fellow poultry-keepers, keeping poultry feed secure, and quarantining new birds can help reduce the risk of introducing parasites into the flock. Providing dust bathing areas for chickens is also an effective way to control parasites, as it helps chickens maintain their skin and feathers.

Stress
Chickens losing feathers and developing bald spots is a natural occurrence, usually attributed to moulting or feather pecking. Moulting is a natural process that occurs once or twice a year, usually in early autumn, where chickens lose old feathers and grow new ones. The process typically begins on the head and neck area, progressing down to the wings and sometimes further. During moulting, chickens may exhibit signs of stress, such as withdrawn behaviour, paler complexion in the face, comb and wattles, and a cessation of egg-laying. This is because feather regrowth consumes all available nutrients, making it crucial to provide extra care, high-quality nutrition, and supplementation during this period.
Feather pecking is another common cause of bald spots in chickens. It is often associated with establishing the pecking order within the flock, where dominant chickens may peck at the backs of the heads of more submissive chickens. Additionally, feather pecking may be a sign of stress in chickens, indicating discomfort or bullying within the flock.
Other factors that can contribute to feather loss and bald spots in chickens include parasites such as lice or mites, which can irritate the skin and cause chickens to scratch or pull out their feathers. Heavy lice or mite infestations can lead to feather loss and bald spots, especially if the chicken is constantly scratching or pecking at the affected areas.
While moulting and feather pecking are the primary causes of bald spots in mature chickens, other factors such as stress, nutritional deficiencies, or parasites may also contribute. It is important for chicken owners to monitor their flock for any signs of abnormal feather loss and take appropriate measures to ensure the health and well-being of their chickens.

Poor nutrition
Bald spots are common in chickens during moulting, which is the natural, regular shedding of old feathers and the growth of new ones. Moulting usually occurs once a year, often in autumn, but can also be triggered by a sudden change in daylight hours or temperature. Chickens may also lose feathers due to feather pecking, which can be caused by boredom or a lack of food.
Feather pecking is a behavioural problem that can develop when chickens are bored or do not have enough to peck at, such as food. Restricted feeding programs, where chickens are fed at specific times rather than having constant access to food, can contribute to this issue. Chickens that are not free to feed throughout the day may become bored between meals and turn to pecking at their own feathers or those of their flock mates.
Additionally, an unbalanced diet can lead to nutritional deficiencies, causing aggression and problem pecking behaviours. Feeding chickens too many treats, snacks, or kitchen scraps can interfere with their daily nutritional requirements. Chickens require access to nutritionally complete feed appropriate for their age and should limit treats to no more than 5% of their total daily diet.
Malnourishment can also occur when chickens are allowed to selectively eat from their feed, picking out certain bits and leaving others behind. This can result in a diluted diet that does not meet their nutritional needs, leading to feather loss.
Therefore, it is crucial to provide chickens with a nutritionally complete and balanced diet to support healthy feather growth and prevent feather-picking behaviours associated with poor nutrition.

Frequently asked questions
Yes, bald spots are normal on chicks as they grow. Bald spots are usually the result of moulting or feather pecking. Moulting is a natural process that occurs when a chicken loses its old feathers and grows new ones. It is common for chickens to have bald spots during their moulting period, which typically happens once a year, usually in early autumn.
Bald spots on chicks can be caused by several factors, including moulting, feather pecking, stress, poor nutrition, disease, parasites, and preening. Moulting is the most common cause, as chickens naturally lose their old feathers and grow new ones annually. Feather pecking can also result in bald spots, as chickens may peck at each other to assert dominance or due to bullying within the flock.
To treat bald spots on your chicks, you can take several measures:
- Ensure your chicks have a high-quality diet and easy access to food and water.
- Provide supplements such as vitamins and biotin to support feather regrowth during moulting.
- Reduce stress by maintaining a consistent routine and addressing any known stressors.
