1. Spooky Spectrum Sweep is always a good idea. If your gut flora gets affected, simply use probiotics to replenish.
Having an infestation, it would be pretty easy to get some specimens with the help of duct tape.
You have some very effective presets for mites in Preset Collections>Environmental>Remote that you could also try.
Hulda Clark talked about using ozone to treat mite infestation. She suggested a sauna suit made with garbage bags.
Neem oil mixed with soapy water can be used to spray the zones where you used to have the hens, and tea tree topically to get rid of them.

2. There is a Preset specifically for the Ornithonyssus Bird Mite in the Environmental Presets. One can use this in a Remote with a sample of the pest.
If the bird mite in question is a different variety, then may need to use a Spectrum Sweep or Converge Sweep with the sample or with the DNA of the people needing them gone.
We generally do not put human and non-human DNA in the same remote.
