Prob the smartest move. Just know you will have to figure out eventually, if you plan to free range them again, that it won't take long to notice they are out and about. I let the dogs out now and they have succeeded in pushing the predators back...but they are still there. The remaining chickens don't go so far into the woods. So now the pedator will either risk coming in closer, or, move more, or the chickens will forget....
