I'd like to have a flexible ceiling in the new pheasant pen, underneath the 2x4 welded wire ceiling, which is 7' tall. I've never used netting before, but it will be a good addition for this pen and smaller birds. Can you tell me what you've used and liked, and why? Where did you buy it? What advice can you share about installation, how long it lasts, etc.? Thanks in advance for your help.
