Don't sweat it man. Go to mypetchicken.com and enjoy online shopping at its finest. Click away one of these two of those etc... You don't have the big minimum orders there like you do at most hatcheries. The birds you are getting from your uncle, are they gonna be full-time residents or are you just raising them for him to do something with or what? I personally wouldn't use plastic anything. It doesn't seem to last as long and over time the sun will weaken plastic. I'm no expert on the plastic bird netting your are talking about tho, maybe its different. I like to use the poultry netting on my roof and top half of the wall with welded wire on the bottom half of my wall.
