I am about to fence an area for a chicken run. My ckickies were taking over our whole back yard and leaving nice patties all over fun us to step in. We even got "chicken boots" for our 4 young children and "chicken shoes" for us so that our other shoes wouldn't get plastered with chicken muck. So, for the summer, we would like to have our back yard again without needing "chicken boots" for us and all our guests. So, I need to know a height for the fence. Should I make it permanent or temperary with chicken wire/hardware mesh. Mainly, I need a height. Thanks y'all for any input... Johnny in San Diego.
