Field fencing would be the the easiest to put up, and will hold up the longest as well. Green T-post would be the quickest to put up with it. Then if you want or need to move it its simple to pull up and move around.
Cattle and goat panels are really easy to work with, especially if you have fairly flat ground. And they are easy to re-use or move. Sturdy enough to keep bigger predators out for the most part. The only issue I have with them is getting them home! They come in 16 ft lengths, I believe.
Thanks for the ideas. What is "field Fence"? I am thinking it is what we call page wire, but I am not sure. Page wire is a fence that we use to keep in sheep that comes is about 300 foot rolls with small blocks at the bottom and get larger as they go up the height of the fence. Is that what field fence looks like?
