Thanks, they are saying that because it was about 7pm and I just locked them in. They were out all day. It is completely covered with 2x4 fencing to keep the hawks out. Squirrels get through though. I saw one having snack in the feeder once. I was thinking about you wanting yours to go inside at night. Do you have roosts outside that are higher than the ones inside? They all usually try to be on the highest roost. Just a thought.
