Scaly-leg

Why are my chickens’ legs scaly?

Now that our lovely girls are not paddling around in so much mud, it is a good opportunity to check their legs. A healthy leg should have smooth scales with no raised areas. If you are seeing scales lifting or thickened areas, your hen may have Scaly Leg…

This is a condition caused by a mite called ‘Knemidocoptes Mutans’ which burrows under the skin on a bird’s legs to feed on the keratin. The tunnelling irritates with leg scales becoming thickened, as the keratin seeps from the leg tissue, and eventually becoming encrusted and lifting away from the leg. The legs will appear lumpy with large gaps visible between the individual scales.

Scaly leg mites can spread from bird to bird in your flock, so, if one of your hens has developed Scaly Leg, most likely the rest will also be infected. This means all hens should be treated.

This is generally not considered a painful condition but can cause discomfort. The good news is that it is easy to treat.

Symptoms and signs to look out for:

  • The mites burrow under the scales on legs and cause extreme irritation feeding on tissue secretions
  • Initially scales lift if untreated causing crusting, swelling, thickening, bleeding and lameness if severe
  • Mites are spread by direct contact with infected birds

Treatment

  • A thick layer of Vaseline applied daily for a week causes mites to suffocate.
  • Swarfega acts similarly and can assist in removing crusty scales revealing clean, healthy tissue underneath.
  • Daily bathing in diluted mild shampoo or antiseptic allows scales to soften and loosen enabling gentle removal with a toothbrush (repeat weekly).
  • Can use Ivermectin 1% spot on.
  • While you are checking the legs make sure that any leg rings you have fitted are not too tight or damaged.
