You might seriously consider starting over at the new place with new birds come spring, instead of bringing sick birds onto the 'fresh, clean' premises.
It's hard to consider as you're already attached, but you could be fighting it for years if you being it home.
You'll have a lot on your plate just moving.
Are you in a harsh climate?
My first flock was mostly adults because I wanted eggs now, they brought lice, leg mites, and carrying respiratory disease with them.
Had one mild outbreak of the respiratory that was survived with no treatment and little problems, tho it may still be in the flock I haven't seen any more outbreaks. The lice were pretty easy to get rid of with permethrin poultry dust.
The leg mites are still there to some extent but I haven't been real aggressive in treating them.
I was lucky in a way that it was nothing extreme, but still lesson learned,
and I never buy outside birds anymore, just hatchery chicks and hatching done here.
All those original birds are now gone.
