If that netting is 100 linear feet, the enclosed area will be limited to that size......say 4 sides of only 25 feet each? For the same money, you can buy electric fence components and construct your own fence.....one that is much larger and can be fitted to the area you want vs. what you are forced to conform to. Location of corners, etc.
So be looking at the white, step in electric fence posts.......figure spacing at 20 feet apart. If this is to be quick and moveable......consider using poly tape fencing......like this:

So an area that is 50' x 100' = 50' + 50' + 100' + 100' = 300 linear feet. A single 1/4 mile roll (1,320') would allow you to run 4 strands....same length as 3 of the 100' poultry netting fences. You would also need about 20 of the step in posts.
These fencing supplies need not come from Amazon......can probably be found locally. I could buy something like this from at least 5 different stores located 10 miles from me.
If you prefer something more permanent and durable, instead of poly tape, get a roll of aluminum fence wire.....also 1/4 mile spool. But that will also mean upgrades in support posts, etc. So more investment in materials and will require a higher skill level to install, but again, more or less permanent.
