My hens are currently in a chicken tractor that is way too small, they are 7 months old, so we built a new house for them with a temporary run that will hopefully last the winter. Question: If they go in the run most of the time and let themselves in the chicken door, can I let them out the people door to free range if I am home? Will they go in the people door when it gets dark, or will they be confused?? Will they know the house? Or the door??? Thanks!!!
