needing a little advice; I have an old shed on my property which I previously used as a chicken coop but my chickens weren't laying, presumably because there isn't very much light, and there isn't much ventilation. It's completely metal except for half of the side facing their run, which is wood that is rotting away. I'm wanting to put in fencing or something else to replace the wood, but the problem with putting in fencing is I'm not thinking of a way to attach the fencing to the rest of the metal building? Also, I previously used an old hole where there was a window for their access to the coop, obviously if I take out the wooden section than the hole will go away. What are your suggestions for how to deal with this? I am also on a very tight budget. Also, I didn't build this shed and I'm not sure what it's original purpose was, the previous owners of the property where a bit strange.
