I let mine out in the morning before work and they put themselves to bed when they want to, and I close the run door when I get home about 8:30pm. We live in the woods on 7.5 acres and the trees come almost to the house on 2 sides. There are plenty of places to hide from hawks etc under my shrubs or even in my open garage. The other day I went outside and they were all up on my porch sleeping on my Chesapeakes' old dog bed...it was so cute! Anyway, so far it has worked. I know sooner or later something is going to happen, but for now they are happy free ranging chickens. I do have a roo (Rudy Roo) but he isn't old enough yet to be much protection. They have stayed close to the house up to this point in time, but my husband told me yesterday they ventured further than they ever have, over into my neighbors' yard, about 40 yards from my house. Her yard is all open, so if they make a habit of going over there I may lose one or more. We'll just have to see how it goes. It has worked so far, but I work 12 hour shifts so I don't work every day and my husband or teenage son is usually home when I am not.
