My hubby is getting ready to build me a tractor and I have a couple of questions. 1. Does the tin that you use for the top section make it really hot? 2. What size wire do you use and do you just bend it to make the apron or do you hinge it? I ordered Joel Salatin's Pastured Poultry Profits and it should be here tomorrow. I don't know if it will answer my questions but I want hubby to gather supplies tomorrow. TIA!!
