As far as i can tell many of us have had the same worries and fears. Some of us have even crept out in the night with a flashlight to see how they are doing. It is a major hurdle to peace of mind.
I was one of those. For the first 3-4 nights after I put them in the coop I went out several times a night to check of them. I was pretty tiered that week.

. Needless to say I worry....
