Basic Frame.... Forgot to take more pics of frame assembly. Corners from chain link fence material at HD or LOWs. Braces also from same stores. All tubing is 1 3/8 tubing for chain link fence. Wheel design copied from Jaku with a little modification. This eliminates the need for a dolly to move the pen. After pen is moved wheel laid flat and pen rests back on the ground. Simple pin used to hold wheel in place. After chicken wire attached Board to hold door open so I can clean waterer and put trough feeders in and out. First coat of enamel on tubing to make sure it stays cool in the summer. All that is left is to slap on some CoolSeal on the tin and we start on pen 2. It took about 5 evenings maybe 7 hours total to build entire pen.
