Scaly leg is caused by a parasitic mite (Knemidocoptes Mutans) and affects both chickens and other birds. Typically the mite burrows under the scales on the bird's legs but they can also infect other areas, such as the comb or wattles.

The mite spends its entire lifecycle on the birds and is usually spread by direct contact. Birds infested with scaly leg usually have raised or protruding scales, sometimes with a white crusty appearance. Scaly leg is irritating for the infected bird, and in extreme cases can result in lameness.

Local inflammation is caused and the body responds by growing more scales, this happens in a chaotic manner so scales overlap and are not lost in a normal sequence. The scales appear misshaped, dry, crusty, reddened and generally unattractive. Birds may also peck at their legs in an attempt to get at the irritation and if scales are dislodged, areas may even bleed.

This is not a condition to leave untreated, the irritation makes birds miserable, and any lesions on feet and legs are open to infection. Infections in bird’s feet are difficult to treat, the blood supply is not good and healing is usually very slow.

Scaley Leg Mite Treatment

We recommend you try a one of the specialist scaley leg sprays. They are made from blend of natural oils and repellents and are designed to effectively control the scaley leg parasite.

Do not expect an immediate visual improvement, it takes some time for new scales to grow, and in neglected cases even new scales may appear misshapen. It is very rewarding though when a big lump falls away and lovely new scales can be seen underneath. Your birds will also be much happier and healthier.

Remember that dropped scales may remain infectious for up to a month, and it's best to clean and disinfect the hen house, perches, and nesting areas.

If scales come away leaving exposed raw skin I would treat those areas with anti-bacterial spray. Aloe Vera gel is also excellent for promoting healthy tissue re-growth.

Bare in mind that a bird challenged by mite attack requires a good diet, high in protein as growing feathers and skin requires high protein uptake. A vitamin supplement such as poultry tonic can help reduce stress levels and aid recovery.
