We are having a problem. We just started raising chickens. We have 11 egg layers. A farm that has 3 acres and a corn field surrounding 3/4 of our house and then a busy highway. We want them to be free range chickens but lately they have been braver and braver. Now they are venturing into the corn field and getting very close to the road. Does anyone know of any tricks to corral them? We let them out of the coop at 7am or so and don't put them back in until 8pm... Normally at the end of the day they are easy to get back in but in the middle of the day they are very difficult to locate and pin up if we have to leave for whatever reason. What does everyone do?
