BTW, I mentioned locking them up at night because of the probability of predators. If predators are not a problem at your location, then it wouldn't matter so much. Things are pretty calm here, we live in town, but its a very small rural town and the deer and wild turkeys roam freely in my neighbor's rather forested "backyard". He's got about an acre. Coyotes are evident at times, never bothered us, which makes me happy. I do lock mine up in secure/covered pens at night. For one, I feel they are safer and secondly, I don't let them out until 9 or so the next morning and most of the eggs are laid in their pens where I can find them!
