How do you have your run enclosed? We will be building a run starting sometime this month (hopefully!). So far we just let the chickens out of their coops, we have two of them, into the backyard to roam around in the afternoons. The only problem is that we now have a chicken-chasing dog who I am sure would grab one of the chickens given half a chance. I am looking to build a run about 10x15 and tall enough that I can walk into it without having to stoop. I'm trying to figure out the best way to do this and would love to hear how others have enclosed their runs. Thanks!
