New coop, new chickens and MITES!

[kmart60]

Help! We just picked up our first ever chickens, and as they were handed over the seller calmly noted that they had mites and she had dusted them.
Yikes! Should we put them in their brand new, mite-less coop, or knock up a temporary shelter until we eliminate them? We bought some powder and also a wash, not sure if we should use both?

They are so sweet. But I wasn't prepared for issues from Day 1.

Hmm, what type of mites? feather mites or leg mites?

I think they must be feather as she's dusted them all over. With this...

And told us to use the wash on the coop. Because of covid lockdown, only one of us could go pick them up, unfortunately the husbana doesn't get into details. He said she told him we wouldn't properly get rid of them until the warm weather arrives (currently in locked down, wintery, rural NSW Down Under).
I'll check out the link in your other post, thank you.

I don't know what's available where you are but I have had good luck with permethrin here in the US. It does take weekly treatments of 3 or 4 weeks because the insecticides will not kill the mite's eggs but will as they hatch out so the weekly treatments are necessary. I thoroughly spray everywhere in the coop. I put poultry dust in the nest boxes. Good luck...
I don't know if these are available to you but should work. I don't know the pyrethrum mixture. Permethrin is the synthetic version.

Pyrethrum (Permethrin) can be used anytime of the year and the bonus is there is no egg withdrawal period so the eggs are safe to eat. Again, good luck...
