I have a small flock of 12 chickens. They are about 2 months old. We moved them into their coop about 2 weeks ago. At night, they don't go back inside. They bed down in a shaded area under the coop. (It's an A-frame, with an open area underneath.) Every night, my boys and I go out and put them inside the coop and lock them in for the night. First thing in the morning, someone goes out and let's them out. Any suggestions on getting them to go back inside when it starts to get dark? I would eventually like to allow them to free-range, but am unsure if they can be "trusted" to return to the coop at night. If they don't make it back, they will surely be food for a neighborhood predator (raccoon, skunk, fox, etc). TIA for your help.
