I often have people want to come see my chickens and i struggle with the worries of bio security and all. Thought I'd share this idea with you. I use plastic grocery bags when ever people come into my yard. When they first pull up I have some handy or I request that they bring some, so that way they can put their foot in and tie it up around their ankles................ instant bootie! It may need to be doubled up in yards with thicker brush etc... but here in Fl sand or on grass it works great........... and it's a good way to get another use out of those baggies.
