Well, I quit kissing our chickens
Seriously though, although the flu is deadly I have to many other things to worry about on any given day that are closer to home.
A few years ago the huge scare was West Niles, I actually had two horses that contract it fairly severely and we nursed them back to health, I'm sure more of our horses were also exposed but had minor/no reaction. A healthy immune system is the most important thing is animals and humans.
I'd just about bet I've been exposed to the West Niles, EIA, etc. All part of life on a farm.
