I have read over the many years of bird keepers lung. I have always changed my parrots cages every day or every other day because of these stories. I can give you two personal stories about this. Both times I was told my birds had to go and both times it came out that they were not the problem. I did not have psittacosis, and my husband did not have bird keepers lung. I applaud your commitment to your parrots. It is a rare and wonderful thing. I have eight geriatrics in my home, not including the husband. Lol
Did your doctor do a lung lovage? Are they really sure this is the problem, and are you willing and able to do some modifications if necessary to avoid losing your parrots?
I was initially diagnosed with Interstitial lung disease and as soon as the Pulmonary MD. found out that I have 2 parrots, he focused on that being the problem. Two tests indicate that I am allergic to the parrot droppings but not the serum and not for canaries, parakeets, cockatiels pidgeons, chickens. I am now wearing gloves and a mask when I am feeding them and changing their paper, etc. MD. said that is not enough and wanted me to separate myself for 2-3months to see if that would make a determination (totally out of the question). I believe my lung condition is a result of chemo treatments for breast cancer since the early symptoms began after completion of treatment. The African Greys are like my kids and I won't just get rid of them without more evidence. Thank you for your input. Will be tested again in June to see if the nasal steroid and gloves and mask are making a difference.
