We also had a thunderstorm the other night. I had a chicken that was in broody jail in the run., I too worried as there was such a load thunder boom right over the property. I thought she could have a heart attack from this. As I knew I had to wait until the next morning to check on her. She was fine, but let her out since I felt so bad. As she only spent one day and night there. This diffidently stopped her being broody. Anyway I was talking to the guy who built our house and was the first owner. He told me about a lightening bolt that went up a tree in front of our house went into the formal living room and damaged rocks on our fireplace. He stated he was told if he was in that room he would of been killed.
