We have began building our working pens. Last year we found plans from OU. Made money off of hay this year and time was right. Set post last weekend and my son began welding during his spring break. So glad he was willing to help us out. Next, we will be building in a tub. I don't know how long it will take, but not a fast process for us. Below is a video of our progress.
