I have a 10'x8' shed that I want to convert to a coop. Now this shed is located in a half acre field that is fenced in with a chain link fence that is 5' high. My questions to you poultry professionals are: Will the chickens come back to their coop at dusk or will they sleep in the field? (Field is just mowed grass, no shrubs or bushes) If I clip the wings do I still have to worry about chickens getting over the 5 foot fence and into my neighbors yard? Basically I just want to know if I am forced to build a run even though I have a 5 foot fence all around the field. Thank you so much!
