Hi, We have just started out Backyard Chicken Flock. We're confident in the security of our coop, but have questions about our attached run. As of right now we are using sharpened cedar fence posts and poultry netting without a top. Obviously, this isn't too secure as anything could get in and birds could fly out. We are planning on putting our in the run from around 7 a.m. to 3 p.m., then free ranging them when we get home from work and shutting them into the secure coop at night. How risky is that daytime stretch when they are in the not-very-secure run? The chickens will have access to under the coop to protect them from flying predators, so the main worry would be ground predators. How killer are they during the day? We're a heavily forested area in the White Mountains of New Hampshire. Thanks! Picture below is our coop minus the run.
