I am now considering making a corner of my detached garage into my chicken coop and then just cutting a chicken door into the side. The door will go to a probably 4-5x8-10 run, probably only 2' high. My question is, I have gas cans in the garage for lawn equipment, would this be bad for the chickens? Most of the cans have caps on the spouts, but I just want to make sure I am not contemplating something that could be harmful for my chickens. Also, if I do this in the garage should I put a window in the garage? I would think I would almost have to for ventilation in the summer, right? Since it is detached I would probably have to add a heat lamp during the winter too I guess.
