3 hours sounds too far for that to reasonably work. Some BYCers report have “self-sufficient” flocks that can be fine for up to a week without tending. However, they are at home. The owner either has a busy alternating schedule or has to travel, which is why they setup the chickens this way. The coop and run are treated as one where it is all very secure from predators (no free-range) and are often 24/7 setups where coop is open to the run -no auto door. Flocks are not very large. There is enough water and food for longer than expected and rodents are managed so they are not eating the food.
In your situation, it seems a high of a probability that a crisis could occur with the chickens.
ways to make that work: hire a person/neighbor to daily check flock health, water and food, and run security (no breeches), also they should collect the eggs. Install a camera or two to monitor the area and flock For your own knowledge.
Enjoy your quail! We had them for awhile and loved the small eggs-so versatile!
