I am seeking easy cheap way to have home for chickens. I am going to be moving and there is a little barn looking storage place out side i was thinking I could use. But then no way for them to get outside to eat grass or get fresh air. Not sure how to put fencing on and around it so the chickens don't get lose. I do have like 12 foot fence so they can't get out the yard I don't think. But It still worries me anything thoughts?
