Thanks for the prompt response, Mary. We will go ahead and use U staples. Found a fantastic fence at the end. It is welded, but is hinged in last 500mm on the top to bed outwards for further protection and matching hinged skirting that bends outwards. Fingers crossed all goes well!
Interesting method. Do you think I could I use washer and TEK screws when using a welded wire mesh of gauge 14? We are building our first chicken run (and we are not very strong at DIY).
