Hello all! We are getting ready to put our girls into their new coop and run. My question is, when it comes to coop training, do you have to lock them in the coop only for those few days? Or does locking them in the coop and run work as well (i.e., no free range time)? Also, do most people lock their girls up at night in the coop even if they have a good, predator resistant run? TIA!
