We go away for the weekend twice a month during the summer, sometimes more. When we do these shorter trips I keep the chickens in the coop with the 5gallon feeder full of food and numerous waterers full. I have a 3 gallon waterer/5gallon waterer/ 2 5 gallon buckets for the ducks/geese and 3 rabbit waterers. If it's a terribly Hot weekend, then I ask our neighbor to let them out in the morning and shut them back up in the evenings but otherwise they are fine.
When we took a 10day trip this summer, we did have the neighbor come over and water/feed them and he enjoyed it. But I don't want to take advantage of him and it to become a burden on his already busy schedule so I try to make them self sufficient!!
It will be another long weekend away again and they will be just fine, the temp's have been cooler for us this summer so we should get by without the neighbors help!
