I want to buy some of the movable electric netting that free-range operations often use to corral their birds. Does anyone have a good source for the netting? I looked online and feel that the first couple hits from google were wildly more expensive than what I thought it would be. I mean, if it costs as much as I was finding then how do all the little organic farms and hobby growers afford what is apparently several thousand dollars worth of the stuff? I just always viewed it as a more affordable option, which may be a misconception on my part. If you use electric netting, where did you get yours?
