Hi cgrn, I'm located at the Jersey Shore, in Brick to be exact. Too far from you, but I let my chickens have access to their run from the coop so they can get out and stretch their legs in the morning. Then I collect eggs, usually before 8:00 am. I have hardware cloth under the run and attached securely to run. I have had no predators (YET). I chain lock the doors to the run. I would be surprised if anything got in, but I worry, so I always check. Good luck, you should find a friendly chicken person to help you out, so you can have a relaxing, fun vacation without worries!
