Scaly Leg Mite in Chooks
Scaly Leg Mites
Scaly let mite are a common external parasite which affects poultry. The mite, Knemidocoptes mutans, burrow into the skin on the chook’s legs and the tops of their feet. The mites eat the flesh under the scales on the leg and feet and leave droppings behind, resulting in thick, crusty legs and feet. If left untreated the legs and feet will become so crusty that they will suffer from reduced mobility, potential loss of toes, and permanent deformation of their feet. If one chook is infested with scaly leg mite it likely that all your birds will be, and it is important to treat the whole flock to prevent an ongoing problem.
Treatment Options
To suffocate the mites and help promote healing, start by cleaning the chook’s feet and legs in warm water and gently scrub away dead and loose scales. Next coat the legs and feet in an oil such as linseed, mineral, olive, or vegetable. Wipe off any excess oil and apply a coating of Vaseline. Repeat this each day until new, healthy scales begin to grow.
Alternatively, an Ivermectin-based product (as found in cattle drench) can be used, however is not registered for use in poultry. This product absorbs through the skin and eventually makes its way into the skin tissue where is will be consumed by the mites. It also kills any internal parasites such as Bear in mind that the Ivermectin will also end up in the eggs and how long eggs should be withdrawn from human consumption is at the owner’s discretion.
There are many ‘traditional’ remedies for scaly leg mite which include the use of petrol, WD40, kerosene, or other solvents. These can be toxic to the skin and will be absorbed into the bloodstream potentially damaging the liver and kidneys of your poultry.
