I ended up buying a 10x12 ft former construction office buidling for cheaper than I priced the lumber to build a coop of the same dimensions. It has 3 windows, vinyl siding, insulation, drywalled, and electricity. I'm going to put hardware cloth around the foundation 12 inches deep? and build an attached run. My chicks are 7 weeks old now and are curently in the basement so I need to finish this quickly. My question is, Since the foundation will be secure from predators, do I need to put hardware cloth across the windows? They are about 5 ft from the ground and I don't know what could scale the side to get in. They currently have window screens. I planned on just using the front door to let them in and out with a ramp. I wanted to avoid cutting a hole in the building for a pop door because of the electric outlets. (there are 11). I will cover the outlets with child protective covers . Does this sound okay? Also, I know this question is in the wrong place but, I plan on letting them frre range when I'm home. Are cats a problem or can the chickens defend themselves against them? I have 2 barn cats. Thanks for any assistance you can give.
