I live in town on an acre lot, I have trees around my property but no fence and I really enjoy letting my chickens out a few times per week( I would like to let them free range but can't) I have neighbors all around me so I have to keep them close. Right now I let them out about an hour before they go to bed so that they will return to the coop on their own. Also I have a bell that I ring every time I feed them / give them a treat in hopes that they will hear that bell and come running. This doesn't work all the time. Does anyone have any other ideas as to how I can round up my flock when I need to?
