Lice and mites are common external parasites that affect poultry. They are often introduced to chicken yards by wildlife, especially wild birds. Lice are tiny, wingless parasites that feed on the keratin in chickens' feathers and skin, while mites are bloodsuckers that can burrow into the skin. Both can cause discomfort and health issues for chickens, including decreased egg production, weight loss, and even death if left untreated. Therefore, regular inspections and good sanitation practices are crucial to prevent and treat infestations. When lice or mites are detected on one bird, the entire flock should be treated to prevent further spread.

Mites and lice are spread by wild birds, rodents and other animals
Mites and lice are a natural part of life for those who keep chickens. They are spread by wild birds, rodents, and other animals, and can easily be passed on to chickens that spend time outdoors. Mites and lice are most commonly brought into chicken yards by wild birds and other wildlife.
Bird mites are parasites of poultry and wild birds. They live on a wide variety of domestic and wild birds, including poultry, pigeons, starlings, sparrows, and robins. These mites typically remain on birds or in bird nests throughout their lives. Mite eggs are laid in nests or on feathers and hatch in two to three days. Bird mites are active during the summer and can bite humans as they search for hosts, but they cannot reproduce on human blood. They are very small (about 1/32 inch long) but are visible with the naked eye. They can vary in color but are generally brownish or grayish and may appear darker after feeding.
Poultry lice are fast-moving, 6-legged, flat insects with round heads that live only on the chicken and its feathers. They are beige or straw-colored and are typically found at the base of feather shafts near the vent. Poultry lice feed on dead skin and other debris such as feather quill casings. They do not suck the chicken's blood like mites do. Lice spread quickly among chickens, so all birds should be treated even if only one shows signs of infestation.
To prevent infestations of mites and lice, chicken coops should be cleaned regularly, with loose feathers that can harbor hatching eggs disposed of. It is also important to limit visits from fellow poultry keepers who may inadvertently transport mites and lice on their clothes, footwear, or equipment. Chicken feed should be kept in a secure location to avoid attracting wild birds, which can carry parasites and diseases.

Signs of infestation include: dirty vent feathers, decreased activity, pale comb, changes in appetite, weight loss, bald spots, etc
Lice and mites are a natural part of every backyard. They travel on birds, rodents, and other animals, so when your chickens become infested, it doesn't mean you're not keeping a clean coop. However, it's important to recognise the signs and symptoms of an infestation and know how to treat them. Some common signs of any type of mite or lice infestation in a chicken include dirty-looking vent feathers, decreased activity or listlessness, a pale comb, changes in appetite, weight loss, feather-pulling, bald spots, redness or scabs on the skin, and crawling bugs on a chicken's skin or nits on feathers.
Dirty vent feathers demand a closer look. Mites and lice are most commonly brought into chicken yards by wildlife, especially wild birds. Mites can be grey, dark brown, or reddish in color and can often be seen along feather shafts and underneath roosts after dark. They are also partial to cracks and crevices in wood, roosts, and inside nesting boxes. Red roost mites are active at night when they venture out to leech blood from chickens. The vent area is a favorite feeding ground for mites, so keep a close eye on this area. Typical signs of a mite infestation are scabs near the vent, eggs on the feathers and feather shafts, and a light-colored bird's feathers may appear dirty in spots where the mites have left droppings and debris.
A chicken's comb is a good indicator of its general health. If your chicken's comb is unusually pale, it could be a sign of anemia, typically due to parasites, heat exhaustion or dehydration, stress, or frostbite. A pale comb may also be a warning sign of a more serious illness, as diseases and infections that affect the circulatory and respiratory systems can cause the comb to appear pale.
Weight loss in chickens can be hard to tell if you don't handle your birds a lot, as feathers tend to hide a wasting chicken. However, rapid weight loss and decreased appetite may indicate air sac disease or Marek's Disease, whereas gradual weight loss, despite a good appetite, may indicate Avian Tuberculosis or Marek's. Stress is a leading cause of weight loss in chickens, as environmental changes, predator encounters, or overcrowding can stress hens, reducing their appetite. Intestinal worms and other parasites can also deplete chickens of nutrients, even if they're eating well.
Bald spots are usually the result of moulting or feather pecking. Moulting is perfectly natural, and a chicken's first moult is shortly after they hatch. However, if it's not autumn and your chicken has wounds alongside bald patches, it could mean that there is a bully in the flock, or the chicken herself has pulled her own feathers, which could be a sign of discomfort or a heavy lice or mite infestation.

Northern fowl mites and red roost mites are two of the most common poultry mites
Mites and lice are most commonly brought into chicken yards by wildlife, especially wild birds. They are a natural part of every backyard, travelling on birds, rodents, and other animals. Therefore, a chicken coop should be cleaned regularly, with particular attention paid to disposing of loose feathers that can harbour hatching eggs (nits). Northern fowl mites and red roost mites are two of the most common poultry mites. These eight-legged mites can live on chickens and in the coop. They are grey, dark brown, or reddish and can often be seen along feather shafts and underneath roosts after dark. Red roost mites are partial to cracks and crevices in wood, roosts, and inside nesting boxes. They are nocturnal and feed on blood. They are usually not found on birds during the day, but hens sitting on eggs may be attacked.
Red roost mites are the most common type of chicken mites and are found worldwide, particularly in warmer climates. They are a particular problem in poultry houses with wooden roosts. They can cause birds to become anaemic, lethargic, and exhibit a pale comb and wattles. Feed efficiency and
Signs of any type of mite or lice infestation in a chicken include decreased activity or listlessness, pale comb, changes in appetite, a drop in egg production, weight loss, feather-pulling, bald spots, redness or scabs on the skin, dull, ragged-looking feathers, crawling bugs on a chicken’s skin, or nits on feathers. Monthly or bi-monthly flock inspections of each chicken should be performed to identify and address parasites before an infestation worsens.
To prevent infestations of lice and mites, keep poultry feed in a secure location so as not to attract wild birds, which can carry parasites and diseases. Always quarantine new birds for at least two weeks before introducing them to an existing flock to watch for parasites. Provide adequate dusting areas for chickens to care for their own skin and feathers naturally. A dust bath is the chicken equivalent of a daily dirt shower, helping them maintain their skin and feathers and control parasites. Some claim that adding food-grade diatomaceous earth (DE) to the dust bathing area combats external parasites. Ivermectin and Permethrin can be used in conjunction with Elector PSP to effectively eradicate poultry lice and mites. The coop needs to be thoroughly cleaned and sprayed with Elector PSP prior to allowing the treated chickens back into the area. Other more natural treatments like neem oil, apple cider vinegar, or First Saturday Lime can also be part of the solution.

Treatments include: Ivermectin, Permethrin, Elector PSP, apple cider vinegar, neem oil, etc
There are several treatments available for chicken lice and mites. Here is some information about the treatments you listed:
Ivermectin
Ivermectin is an injectable treatment for chicken lice and mites. It can also be used topically and orally. However, it requires an eight-week egg withdrawal period.
Permethrin
Permethrin is a synthetic version of pyrethrins, which are natural insecticides. It is available in concentrate and powder form and can be used to treat lice, mites, ticks, and bedbugs. It is safe for use in poultry housing. When applying the powder, avoid getting it on the chicken's face, especially its eyes, and avoid inhaling it. Traces of permethrin can remain in egg yolks up to 21 days following treatment.
Elector PSP
Elector PSP is a poultry veterinarian-recommended treatment for chicken lice and mites. It is available as a 9 ml concentrate that must be diluted with one gallon of water. It can be used to treat at least 50 chickens. It is safe for both chickens and humans and does not require an egg withdrawal period. It acts as both a larvicide and an adulticide, killing adults and their nits after a single application.
Apple cider vinegar
Apple cider vinegar has been used for centuries for medicinal and therapeutic purposes. To use it for mite control in chickens, add one tablespoon of apple cider vinegar to each gallon of water. This can be done for one week out of each month. Alternatively, if your chickens have an active infestation, you can fill a dish tub with water and add one tablespoon of apple cider vinegar for each gallon of water. Place the infested chicken in the water for 20-30 minutes and gently rub at the base of its feathers, paying special attention to the area around the chicken's vent and neck.
Neem oil
Neem oil can be used to treat chicken lice and mites. To use it, create a solution of 5% neem oil in water and spray individual chickens or dunk them in the solution if you have several to treat. It is important to regularly clean out the nesting boxes to prevent reinfestation.

Dust baths are a natural defence against parasites
Mites and lice are common external parasites that can affect chickens. While it is natural for chickens to have some parasites, large infestations can lead to serious health issues and even death. Therefore, it is important to be able to recognize the signs and symptoms of an infestation and treat them effectively. Some common signs of mite or lice infestation in chickens include decreased activity, pale comb, changes in appetite, weight loss, feather-pulling, bald spots, redness, scabs on the skin, and dull, ragged-looking feathers.
Dust baths are a natural and effective way to prevent and treat external parasites in chickens. By providing a designated dust bath area, you can help your flock maintain good hygiene and keep their feathers clean and functional. Dust baths help to absorb excess oil and moisture, which can reduce the amount of feather lipids and help control parasites. The soil, sand, or wood shavings used in dust baths can also get rid of mites and other external parasites. Additionally, food-grade diatomaceous earth can be added to the dust bathing area to further combat external parasites.
Chickens will instinctively seek out sunny spots to create their dust baths. They will scratch and bill-rake at the ground, erect their feathers, and squat. Once lying down, they will shake their wings, rub their heads, and scratch with their legs, working the dust through their feathers. After the bath, they will thoroughly shake their bodies to ruffle their feathers and may preen using their bills. This behavior is not unique to chickens, as many other bird species, such as wrens, house sparrows, and quail, also practice dust bathing.
In addition to its parasite-fighting properties, dust bathing is believed to serve other functions as well. It may help with thermoregulation, providing a sunscreen, scent-marking, and maintaining good feather alignment. While it is primarily studied in birds, dust bathing is also observed in other mammals such as chinchillas, long-eared jerboas, and possibly Belding's ground squirrels.
To create a dust bath for your chickens, find a sunny spot in your yard and fill it with sand, soil, dirt, wood ash, or just about any type of loose material. If you don't have access to an outdoor area, you can build a simple wooden box without a lid that is about 6 to 12 inches tall and fill it with soil or sand. By providing your chickens with a dust bath, you can help them stay clean, healthy, and parasite-free.
