Hutch should work if ventilation added. (did not see any) You have what you need for fencing, BUT: Dig a trench and pour cement in it after setting and stretching fencing. Will lock it down good and should be ok unless you have sandy soil. If sandy soil then attach an 18" wide roll of 2x2 welded wire to bottom of fencing after it is installed and lay it flat and them cover it with an inch or two of dirt. Then take 24" roll of hardware cloth mesh and surround the pen at ground level to keep coons from decapitating your chooks. Then install a fence charger and 4 strands of hot wire all around to discourage coons or coyotes or some dogs even from climbing in. Overhead protection is optional, but be aware that hawks and owls really love chickens, especially small young ones.
