I am new to chickens this year. So far so good. We have 3 BR & 2 BO that are 8 weeks old. We put them outside a few weeks ago and all is going well. Our run is built around the coop and have been locking the girls in the coop at night. They are out by 6am & go in at 7:30-8pm. The door to the run to as secure as we can make it. They are in there all day while we are at work and no problems. We live in the N. GA mountains on 11 acres...so predators will be a issue. We have not had any problems so far. The question is, do we need to lock them in at night or can they stay in the run. I don't think anything can get in thru the door. I guess the question is, are they getting enough daylight. Please help!!
