I've a smart hawk after my little flock and after keeping them in their enclosed run that's about 15 x 15 for three days I just had to let them out to forage. They hate being shut up on that run for days. I'd like to put game bird netting over my back yard area but it's a big area... forty feet by about forty feet. I'd need netting that could support snow and ice load and I want to prop it up with metal or wood supports so I can walk underneath it in places. $$$ Does anyone have game-bird netting around their large runs and where did you get it? I've regular deer netting over the small run area. Fine for keeping out hawks but it won't hold up to snow load.
