Where to buy net?

[ukrkoz]

I am likely to end up fencing part of my backyard to contain our flock. I am very very likely to end covering it from the top, we live next to trees in rural.
Where do I buy nets reasonably priced and large enough to cover about 8 000 sf? Surely used fishing nets sound about the best, but I am clueless where to look. Seattle area.

2 of those should easily cover what we need.
