So far, my chicks haven't been out of the run at all-it's attached to the coop and they just run back and forth. I've been locking them into the coop at night-they're really good at going in when we approach the coop/run. The coop is secure with hardware cloth around the sides, so no digging! My question is this-since the door to the coop itself is a ramp, and I'm not an electrician (so automaticity is eluding me at the moment), can I leave the ramp down so they can come and go if I'm out of town? And if I did that, should I put a light out there? Just looking into the future....holidays and such.
