I'm currently building my 9th and 10th coops to sell. 9 is sold 10 is display. But boy it sure can be DANGEROUS work. I put a 1.5" industrial type staple through my thumb today. a Month ago I put a big honking nail through the finger next to my currently injured thumb.
All I can say, is it's a good thing I have a doctor living next door or these coops would be really expensive
Might be cheaper to invest in a good set of clamps
