poultry net?

[guzieae]

I'm looking for a large net that I could hang from a tree in our yard...I'd like to secure the bottom and allow the girls to "free range" a bit in our backyard but still keep them safe and from flying over the fence. Any ideas or links?

It's called aviary netting. Many places sell it, and there are dozens of various quality/size of nets
