Hi, I need to go out of town Friday through Sunday and need to leave my girls home alone, they will be almost 15 wks old. I do not have a neighbor to check on them & let them out . I have a small chicken coop and run. The coop part is 4 feet by 3 feet and the run is 4 feet by 6 feet. Do I need to leave the girls in only the Coop or can I leave the door open to the Run portion? It is built with hardware cloth & has one small window. I do have an additional 6_12ft dog kennel attached but the girls would not be in there while we are away.
