What doesn't kill you, only makes you stronger. IF YOU ARE THAT WORRIED ABOUT GERMS, MOVE INTO A STERILE BUBBLE!
Ok, if you get my drift, it is what it is, chickens and farms and pets, OHMY! They have hair, germs and dander. Get over it. While you would not EAT chicken poo, rest assured you will contact it and everything else that is Mother Dirt too. Simple changes in life style about laundry and hand washing, changing farm boots for shoes inna house, well, it is just thinking and living diferent. Hospitals are terrible places to be sick, they have ALL the forms of germs. Most germs in nature have benefitial effects, even if they are terrifying when they get out of whack. Our human body reads the invaders and takes care of most of them, over time. So dont be stupid about exposure, but dont worry about the normal risks either, Nature the Mother is always watching over her flock, and it includes me and you.
