I have plans to add a second 10X10 chainlink run to the existing one. I don't want to remove one wall of the existing run--instead, I want to leave that wall there and have a chicken-access door through the chainlink. The idea is that the chickens would have limited access to the second run, which would, hopefully, then stay somewhat grassy. I am working on mud eradication for the first run, and they would be confined to that run enough to keep them from completing destroying the grassy run. I could keep them off it to re-seed, etc. (I only have 3 chickens, BTW). But I cannot figure out how to make a doorway through the chainlink! If I cut a hole in chainlink, it will just be an amorphous hole with no form to it. Nothing to which I can attach a swinging door, etc. Do you see the problem? Does anyone have a solution?
