Scaly leg mites are tiny, microscopic bugs that infest the legs of chickens, causing unsightly and uncomfortable symptoms. These critters dig under the skin of a chicken's legs, targeting keratin. As they burrow, the mites cause the scales to thicken and flare up, eventually becoming crusty and peeling away from the leg. This results in thickened, scaly skin, raised non-uniform scales, white crusting, and seepage of tissue fluid. The mites are spread by direct contact with infected birds, and can cause pain, discomfort, deformities, and loss of toes if left untreated.

Scaly leg mites are tiny bugs that dig under the scales of a chicken's legs
These mites target the keratin in a chicken's legs, and as they work their way around the keratin, the skin flares up as a reaction. This causes the scales to thicken as the keratin oozes out. The mites dig tiny tunnels underneath the skin, eating the tissue and leaving a trail of crud in their wake. The longer they reside under the chicken's leg scales, the more damage they inflict. The tunnelling action of the mites is damaging to the chicken's skin tissue, resulting in hyperkeratotic lesions.
The scales of chickens infested with scaly leg mites will appear roughened, non-uniform, raised, and some may protrude upwards. The legs will look thickened, scaly, and crusty, with some bleeding. The mites cause extreme irritation and pain for the bird, and if left untreated, parts of the chicken's toes may fall off, and heavy crusting of the scales can interfere with joint flexion, resulting in lameness and deformities.
Scaly leg mites have a three-week life cycle and spend their entire lives on their bird hosts. They are spread from bird to bird through prolonged close or direct contact, and when one bird is infected, the entire flock should be treated.

They cause the chicken's skin to flare up, thicken, and become crusty
Scaly leg mites are tiny, microscopic mites that infest the legs of chickens, causing the skin to flare up, thicken, and become crusty. These mites are known as Knemidocoptes Mutans, and they spend their entire three-week life cycle burrowing tunnels under the chicken's skin, specifically targeting and feeding on the keratin.
As the mites burrow and feed on the keratin, the chicken's skin flares up as a reaction, causing the scales to thicken and lift as the keratin oozes out. Over time, these scales turn crusty and begin to peel away from the leg, giving the legs a bumpy appearance with noticeable gaps between the scales. The tunnelling action of the mites irritates and damages the chicken's skin tissue, resulting in hyperkeratotic lesions, which manifest as thickened, scaly skin, raised non-uniform scales, and white crusting.
The mites cause the skin to thicken as a result of the keratin secretion stimulated by their burrowing. This thickening is one of the most noticeable signs of mite infestation, as the scales become noticeably enlarged and lifted. The skin may also exhibit flaking, crusting, and bleeding in more severe cases.
The longer the mites are left untreated, the more damage they inflict. The heavy crusting of the scales can interfere with joint flexion, leading to lameness and deformities. It is important to treat scaly leg mites promptly to prevent discomfort and potential loss of toes or other severe complications.

The mites are spread by direct contact with infected birds
Scaly leg mites, or Knemidocoptes mutans, are a common ectoparasite found in adult backyard chickens, turkeys, and pheasants. These mites are extremely tiny and cannot be seen by the naked eye. They spend their entire lives (10 to 14 days) burrowing tunnels underneath the skin of chickens, primarily on their legs and the tops of their feet. The tunneling action of the mites damages the chicken's skin tissue, resulting in hyperkeratotic lesions, thickened and scaly skin, raised non-uniform scales, white crusting, and seepage of tissue fluid.
The presence of scaly leg mites is irritating and painful for the bird. They are spread by direct and prolonged contact with infected birds, and can also be introduced into a flock through wild birds, rodents, or by already being present in the soil and surrounding environment. As they are spread through direct contact, when one bird is infected, the entire flock should be treated to prevent further spread. This includes thoroughly cleaning the coop and limiting access to wild birds.
The early signs of scaly leg mites include flaking, scaly, crusting, and thickening of the skin on the legs and tops of the feet. The scales of infected chickens will appear roughened, non-uniform, and raised, with some protruding upwards. If left untreated, the condition can worsen and cause necrosis of the toes, lameness, and deformation of the legs and feet. Parts of the chicken's toes may slough off, and the heavy crusting of the scales can interfere with joint flexion.
It is important to regularly inspect your flock for signs of scaly leg mites, especially during the summer months when the legs are more visible. A healthy leg should have smooth scales with no raised areas. If you notice any signs of scaly leg mites, it is important to take action to treat the infected bird and prevent the spread to the rest of the flock.

Treatment options include coating the legs in petroleum jelly, or bathing in antiseptic
Scaly leg mites (Knemidocoptes mutans) are microscopic insects that live underneath the scales on a chicken's lower legs and feet. They tunnel under the scales and into the skin, eating the flesh and leaving droppings that cause irritation. The longer the mites reside under the chicken's leg scales, the more discomfort and damage they inflict. An unchecked infestation can result in pain, deformities, lameness, necrosis of the toes, and loss of toes.
The early signs of scaly leg mites are the appearance of flaking, scaly, crusting, and/or thickening of the skin on their legs and the top of their feet. A normal, healthy chicken should have bright, smooth, uniform scales. The scales of chickens infested with scaly leg mites will appear roughened, non-uniform, raised, and some may protrude upwards.
If you suspect that your chicken has scaly leg mites, there are several treatment options available. One option is to coat the legs in petroleum jelly, such as Vaseline. This can be done after soaking the legs in warm water and drying them with a towel. The petroleum jelly should be reapplied several times a week until the affected areas return to normal. This treatment is most effective for mild to moderate cases of scaly leg mites.
Another option is to bathe the chicken's legs in an antiseptic solution. This can be done by dipping the legs in a diluted antiseptic solution or by using a sponge or cloth to apply the solution to the legs. The antiseptic solution will help to kill the mites and promote healing. It is important to avoid getting the antiseptic solution in the chicken's eyes or mouth, and to rinse the legs with clean water after the bath.
In more severe cases of scaly leg mites, oral or injectable forms of Ivermectin may be prescribed by a veterinarian. Ivermectin is effective in treating scaly leg mites, but it is important to note that it has a withholding period and should not be used on birds kept for meat or eggs.

It is important to keep the chicken coop clean to prevent infestations
Scaly leg mites (Knemidocoptes mutans) are tiny, microscopic mites that live and burrow tunnels underneath the skin on a chicken's legs and feet. They eat the tissue and leave their waste, causing the chicken's legs to appear thick, scabby, and crusty. These mites are irritating and painful for the bird and can lead to severe consequences if left untreated.
In addition to cleaning, providing dust baths and implementing good sanitation practices can also aid in reducing the risk of scaly leg mite infestations. For example, using diatomaceous earth and ensuring chickens have access to dusty dirt so they can take dirt baths can help them handle parasites naturally. Overall, a clean and well-maintained coop is crucial for the health and happiness of your chickens, acting as a frontline defense against various health problems, including scaly leg mites.
