I thought I would be worried, but had no idea the CHICKS were going to freak out this badly. My 3 BO's been in the all in one coop / run for a week all day, in the garage at night with no light. I've put them in the coop part for 15 minutes at a time during the day, without a big deal. Tonight at dark I gathered them easily for their first night out, put them in, closed the door, and then listened to the FREAK OUT. Lunging, body slamming, horrible terrified noises and peeps, scratching, clawing trying to get out. I had no clue this could happen. I went out several times over 20 minutes, peeked in a crack from the nestbox area to make sure none of them were injured / knocked the water over. They were still doing it. I couldn't listen anymore and came in the house.
