We have urban chickens, with, what we hope is a predator proof coop/run (hardwire dug under dirt, which is under pavers that the edge of the run sits atop). Do we need to close up the coop at night? Or can we leave the door between the coop and run open at night? The chickens get restless, around 6:30am, nothing bad, just chirping, and the coop is in a spot that is a bit too close to our neighbors fenceline than code would like. We can move the coop, but would like to be good enough neighbors so that the folks next door don't notice and complain.
