First of all, this is not preaching to eclecktic1. I saw the post and started thinking.... Why stop at disinfecting your shoes just at the feed stores? Do we think chicken people don't go to restaurants, banks, grocery stores or shopping? I'm also sure people who don't own chickens go to parks, feed the ducks and geese, take walks in the bird laden forests and then go to all sorts of places, too! All with the same shoes! And the same car tires! We can't control where birds fly or who has what on the bottom of their shoes or car tires when we are talking about EVERYONE in our communities who go here and there could carry diseases with them! I'm just not going to obsess over this. It will take the fun out of my chickens! Just saying.....What about old fashioned disinfectants like ammonia for shoes? I wouldn't necessarily want to use it for the coop because of fumes and sensitive avian respiratory systems, but for disenfecting shoes after a trip to the feed store?
