I'm currently planning my chicken coop and run, but I keep running into the same issue... I don't know how tall to make the run! I keep seeing people saying that theirs are 4, 6, or 8 feet tall, but what is the minimum? I have fencing that I want to reuse that is two feet (actually more like 2.5) and two feet sounds small, but it looks like plenty of head space. I am covering the entire top with hardware cloth, so it's not a matter of needing height to keep them in. I just want to make sure they're going to be comfortable within a two foot high enclosure. I also like the two foot (2.5ish) height because I can easily step over it and my plan is to make the top removable, so I can walk in when I need to. Thanks for your help!
