My sister and I are going to the county fair tomorrow evening and I would love to go through the poultry barn to check out the chickens. Being a flock owner, is this safe? How likely is it I could bring a disease home to my chickens? Is it as easy as something coming home with me on my shoes? About 2 or 3 years ago they cancelled the poultry show due to avian flu. I guess that has me a little paranoid...
