Ivermectin is a topical treatment that can be applied directly to the affected area to prevent and manage scaly leg mites in chickens.
It's essential to apply ivermectin as directed, typically every 7-10 days for 2-3 treatments.
The medication is most effective when applied in the morning, allowing it to dry before dust bathing.
This helps prevent the mites from being washed off and reduces the risk of re-infestation.

Scaly Leg Mites in Chickens
Scaly leg mites are a common problem in backyard chickens, especially in cooler climates. They thrive in temperatures between 40°F and 70°F.
These tiny mites live on the legs of chickens, feeding on skin cells and causing irritation. They can also cause the skin to become thickened and scaly.
Scaly leg mites are highly contagious and can be spread from one chicken to another through direct contact or by sharing living spaces. They can also be introduced to a flock through contaminated equipment or feed.
The symptoms of scaly leg mites include redness, swelling, and crusting on the legs, as well as a strong, unpleasant odor. Infested chickens may also become lethargic and stop laying eggs.
Treating scaly leg mites requires a combination of good hygiene and medication. Regular cleaning and disinfection of the coop and living areas can help control the spread of the mites.
Treatment Options
Injectable ivermectin is the most effective treatment for scaly leg mites, but it's not approved for chickens and can only be administered by a vet due to its strength and legal restrictions.
Using ivermectin requires careful consideration of the withholding period, which is at least 30 days, and eggs should not be eaten for two months after treatment.
Three doses of ivermectin are given at 14-day intervals to kill newly hatched mite eggs.
You can also use pour-on ivermectin, which is the least messy option and can be applied directly to the skin at the base of the neck or on the back between the wings.

For severe cases or for many birds, ivermectin is a viable option, and it's also effective in treating other types of mites, lice, and worms.
Here's a summary of the treatment options:
If you do decide to use ivermectin, make sure to follow the dosage instructions carefully, such as the Vetafarm Avimec Ivermectin Solution, which recommends 1-2 drops per bird, depending on weight.

Prevention and Management
To prevent scaly leg mites, it's essential to keep your chicken's living area clean and free of moisture. Regularly clean the coop and run to reduce the risk of infestation.
A crucial step in managing scaly leg mites is to thoroughly clean and disinfect the affected area. This includes washing your hands before and after handling your chicken.
By taking these preventative measures, you can significantly reduce the risk of scaly leg mites infesting your flock.
Risk Factors
As we discuss prevention and management strategies, it's essential to understand the risk factors involved. Increased age is a significant risk factor for certain health issues in chickens.

Feather-legged chicken breeds are more susceptible to certain problems. I've seen this firsthand in my experience with backyard chickens.
Recent relocation to a new environment can also increase the risk. This is because the birds may be stressed by the change, making them more vulnerable to illness.
High populations of wild birds in the area can also pose a risk. These birds can carry diseases that can be transmitted to your flock.
Injured, sick, stressed, or malnourished birds are more susceptible to health issues. It's crucial to monitor their health closely and take action if you notice any problems.
Overcrowding is another risk factor to consider. This can lead to stress and increased competition for resources, making your birds more vulnerable to illness.
Here are some key risk factors to keep in mind:
- Increased age
- Feather-legged chicken breeds
- Recent relocation to a new environment
- High populations of wild birds
- Injured, sick, stressed, or malnourished birds
- Overcrowding
