bright red skin and feather loss under tail

[lotsohens]

My first time that I have sick birds, I am heart broken. How best to treat them? I have read to dust them and coop/roost with seven also heard about treating chickens with Ivermecti, orally. Which is best/which works best?

More information and pictures would be helpful. Do you see any visible mites/lice? Do you suspect this is the cause of the red skin and feather loss or is it picking from a flock mate? How old are your birds? What type of feed are they on? You mention they are SICK, what other symptoms do they have?

Have you seen this thread, it kinda sounds like what you are dealing with:

I think they determine it's lice as the conversation continues.

Unexplained feather loss accompanied by red or bright red skin is feather or depluming mites. These mites live in the feather quill, or else infest the follicles that the quill grows from. The feather plucking is done by the bird itself, obviously because of the extreme discomfort that depluming mites produce. Nothing short of a microscope can see feather or depluming mites. Birds with this mite also have an un-kept or tattered look about them

Good article!

So, for depluming/feather mites, the OP is asking about course of treatment. I found a couple of articles, both mention using Ivermectin as an effective treatment. They both do mention poultry dust, but it may not be as effective because powder may not reach the mites burrowed in. OP may also want to clean out the coop and treat it as well.
Hope this helps.

Dipping is a good way to treat for all chicken mites as well as poultry lice. Dipping does require a little skill if you don't plan on getting more mite medicine on yourself than on your chickens.
