We let them free range during the day and are in and out all the time. We live in a small rurual town in Iowa. Later this afternoon I did a head count of my 6 week old pullets and I am missing one. Seriously we watch them out the patio door and we were both in and out all day as well as in and out of the coop. I have no idea whether it was a cat, dog, fox, hawk or what. From now on though they will only be out in their fenced pen unless we are right there with them.
