Dh and I just built the doghouse coop that was featured in Mother Earth News recently. I read on here that people weren't happy with it, but I decided to go ahead and give it a try anyway because I could build it quickly and then have time to make something more substantial later. It turned out well, very sturdy and easy to move, but I'm wondering if I should be putting hardware cloth or something on the outside. The plans say to use 1x2" welded wire for the sides and 2x4" for the top and bottom. (We tried leaving the bottom off, but it was too wobbly without.) After tons of phone calls and internet searches, I am beginning to doubt the existence of 1x2" welded wire, so we made the whole thing with 2x4". Is that going to be enough to keep predators out? They will be shut in the doghouse at night.
