Just go to the TSC site and search wire fencing, you'll find it. https://www.tractorsupply.com/TopCategoriesDisplay?langId=-1&storeId=10151&catalogId=10051
There are many varieties as well as sizes. Most folks recommend against welded wire fencing as it is cheap, rusts, will not last with goat abuse. However, if that's all you can afford, you do what you have to do. You can also use cattle panels (they are 16' long and flexible) to form a holding pen area using T-posts and clips. However, as stated, the cattle panels have 4" x 4" holes above the 2 lowest runs of wire and goat kids can fit right through. So you'd have to back it up with welded wire or some other fencing to make it impassable.
