feather rot help

[/quote] you can also buy a product called ALUGAN this is also for feather mite, but just a long shot are you sure that the birds are not rubing themselves on the drinkers or feeders, please check these loft items to make sure that there are no sharp edges, worth a go. [/quote]

You will find that if a bird is rubbing itself against drinkers or feeders etc that it is because it has these tiny mites that live under the skin in the crop area. Permethrin cream for scabies in humans works but the Flowers of sulphur is cheap and natural and mixed 50-50 with moisturizing lubricant it is a safe and cheap way to cure the birds.
I have cured hundreds here in the Algarve where the lofts have to be very open and the wild birds carry these mites.
It is very rare in the UK but it is there as a friend of mine in Blackpool had it and I told him what to do and it cured his birds too.
Unfortunately a dip of any kind does not always work as the mites are under the skin. Cream worked in to the skin and up under the beak two or three times in as many days (as on the neck and under the beak is where the mites will run once the crop area is treated) will work every time and is safe for the birds as well as very cheap.
