Our 6, 10 week old silkies sleep in a pile in their coop every night. They have a smallish coop connected to a 3 feet by 45 foot run we had our contractor build. The run is completely covered in hardwire cloth. One side of the run is our house the other side butts up to our neighbor's cement walkway. We live 2 miles from downtown Los Angeles in a little neighborhood, so possible predators are urban ones. It wouldn't be possible for a dog or cat to get in. Does the coop door need to be closed at night? I'm asking because we don't let them out of the run until 8am, because that's what time we wake up. I feel like they'd enjoy having access to the run earlier in the morning when they wake up.
