We do it all the time, even a week, never had any issues. We used to just leave the coop door open to a small enclosed run, then put in a solar door that lets them out into their normal large run that’s fenced. Used to lose occasionally to a bobcat (even when we were home), then put a hot wire around the top, grounded to the fence itself, and haven’t since. Knock on wood.
Water on a float system so it’s always full, and a 20lb hanging feeder will keep 8 birds going for a week or so with a little forage. Someone earlier made the point about making sure your feed stays dry—critical. And if you really want to go longer, you might need roll-out egg boxes to prevent them breaking eggs occasionally...but even for a week we haven’t lost many eggs.
