I am newly looking into raising chickens. We have a shed we are turning into a coop, but my question lies in the run. It would be more of a yard, 40 by 50, with the coop within it. I will have a 6 foot fence, with about a foot buried underground to prevent diggers. What is acceptable to use over the top? I wanted to just use the netting like for the game birds. Will that be sufficient? Thanks!
