My nine chicks have it made right now. The place we bought had a large coop with 16 nesting box's and a 16x8 totally inclosed run. There is another run attached that is old and needs some repair but mostly just straighting the fence and putting a gate on it. I decided to let them out into the other run and watch the gate. After about 30 minutes of chasing bugs around 2 of them found a hole just big enough for them to fit through. I let them rome around for a few minutes and then diceded to it was time for them to come back in. Both those baby chicks new exactly were that hole was and ran right back through it. The fence is fixed now, less the gate, but I feel much better about letting them range around the coop in the evenings.
