They are about 12 weeks old, Bantams, and they just got put out into their new run/coop about a week ago. Their hen house is inside the run. I let them out of the hen house in the morning and they spent the day in the run, but I can't figure out how to get them to go back into the hen house at night. People have told me they "automatically go back in at dusk" but not mine. They pile up the corner out in the run. I have to wait until it's well after dark (they're calmer then) and pick them up one by one and stick them in their hen house. Any suggestions on how to get them to catch on to the concept that they should be going inside at night? I talked to one person who said to leave them inside the hen house for several days, but it' not that big and in this heat it doesn't seem like a safe idea to me. What else can I do?
