I have a plastic storage building that is not being used and would like very much to use it for a second coop. Here is a picture I found online of one that is very similar and the same brand. I actually think mine may be a bit deeper. I have moved it up to the run and I can attach it to the run pretty easily. My next problem will be ventilation. I will need to cut windows in two sides for better ventilation. Should I put them up high, toward the top on two opposite sides? Or toward the bottom. I am going to make a door going out one side into the run that will open and close. This think is pretty sturdy plastic but I should be able to cut through it. Have any of you attempted this? Is it going to be too much trouble. I hate this thing just sitting taking up space when my chickens could use it. Any suggestions would be appreciated. Marie PS. We live in the south, so winter is not much of a problem, summer is. Thanks.
