What are your thoughts on this? I work in healthcare and have been told by sereval doctors that owning birds does increase your odds of developing lung cancer/respiratory issues. Today I had a patient that has lung cancer tell me they believe she acquired it in the 4 years she had chickens. It makes me nervous as recently I have been having some respiratory issues, but none of the doctors I have seen have asked me if I own chickens. I'm not trying to start a debate, but would love to hear your opinions. Thanks.
