Causes of scaly leg in chicken ?

Scaly leg in chickens is caused by a parasitic mite called Knemidocoptes mutans. This mite burrows under the scales on the chicken's legs and feet, causing them to become raised, crusty, and scaly. The mites can also cause irritation, inflammation, and discomfort for the chicken.

Other factors that can contribute to scaly leg in chickens include poor hygiene, overcrowding, and unsanitary living conditions. Additionally, older chickens and those with weakened immune systems may be more susceptible to developing scaly leg.

It is important to treat scaly leg promptly to prevent further discomfort and potential complications for the affected chicken.

Mites (Cnemidocoptes mutans)
- The most common cause of scaly leg in chickens
- Microscopic mites that burrow into the skin of the shanks and feet, causing irritation, crusting, and thickening of the skin
- Spread through direct contact with infected birds or their environment

Fungal Infections
- Aspergillus and Trichophyton species
- Can cause crusty, scaly lesions on the shanks and feet
- May be associated with underlying health issues or immunosuppression

Nutritional Deficiencies
- Vitamin A and riboflavin (vitamin B2) deficiencies
- Can lead to dry, scaly skin and other skin problems

Environmental Factors
- Wet or muddy conditions
- Cold and damp weather
- Poor hygiene and sanitation in the coop

Other Causes
- Bacterial infections (e.g., staphylococci, streptococci)
- Parasites (e.g., lice, fleas)
- Trauma (e.g., cuts, scratches)
- Genetic predisposition (some breeds are more susceptible)
