How often to apply vaseline for scaly leg mite?

=First, soak the bird's legs in a solution of warm water with some epsom salts in it to soften the scales. Mites are actually burrowed into the skin of the leg and are causing irritation and build up of stuff which is raising the scales and irritating the skin. The soaking softens up the stuff. You then use a toothbrush to scrub at the legs to remove whatever build up you can. Pat the legs dry.

Then you can either use ivomec 1% injectable topically on the legs, or you can use pour-on ivermectin 5% cattle wormer on the bird - IF - your birds have been wormed within 6 months with a broad spectrum wormer.

Personally, I'd recommend the scrub, worm your flock with wazine 17 (piperazine 17) in the water, and use olive oil on the legs or VetRx daily for 2 weeks then worm them with the pour-on ivermectin (generic, 250ml bottles are the most affordable option). Worming all the flock with ivermectin will kill external parasites as it's likely other birds in the flock have mites but not signs of it yet on the legs. But you have more than one option there.​
