So, I'm currently renting a house on an acre of land. The landlord is the coolest guy ever and told us we could use his shed as a chicken coop (I have five chickens). It works great, and it's a large enough shed to give them some room. I used to give them some time each day to roam the lot and pick for bugs (under my supervision) but now they're getting bigger and more gutsy and they are less inclined to stay close. We have no fence and the road is a busy, 45mph scary one. My neighbor behind me and to my right has a fence, and I'd like to fence off maybe a 50x50 foot area that they could roam in without having to worry about them going to the road. So using my neighbors' fences on two sides, I would need about 100 feet of some sort of fencing. It doesn't need to be pretty, but it needs to be CHEAP and also, it needs to be able to be undone when I move (landlord's conditions). Any suggestions?
