I'm building a small feedlot/ backgrounding lot. I plan to purchase 5 to 6wt calves and grow them to 8wts. I'm wanting some type of fence line troughs, I really want the j bunks, but due to cost I had seen these and thought about building myself some. I'm planning to start with about 15 head and grow to about 60 head at a time. Any feedback on something like this or suggestions.
