@toni1132 We have planted low-growing native groundcover in our yard and next door, and it is irrigated because it is under citrus trees, so there is little dust. The other side it a septic leach field covered with gravel and then native plants, again little dust. Our windows our usually closed and we run a house fan and air purifier. Since we started this, minimal dust inside. On windy days I try to stay in or wear a N95 mask (my brother and I look like twins on those days – he lives across the street and also has lung issues.) A friend handles my bird feeders for me or I mask and glove. I switched from open water for the birds to a chicken-waterer to keep out their droppings and feathers – then I wash hands after I clean i & sanitize it.
Birds in the house have been on our no-go list for years – we had parakeets with psittacosis many years ago and the MD from the state health department told us about the risks because we had ashtmatic kids and an immuno-compromised older adult in the house. Of course we used to make an exception when my daughter's rescue parrot needed care, but even that is past. If you decide to keep your feathered friends, do you have someone else to do cage cleaning? If you must, my ID doc says gloves and N95 mask, then toss the gloves.
