posted on your other post. Is the run covered? Chicekn wire is not strong enough to hold away most overnight predators.
How many chickens?? If you only have a few, create a door and close it at night. When you go camping as long as you have 4sq/ft per chicken in the coop you could leave them shut in with enough food and water for the day, assuming that you have enough ventilation to keep it frmo getting to hot.....
