Helen Holdroyd answered question 6/23/2009 How Long Can A Hen Leave Her Eggs, And Still Have Them Hatch? I had one clocker come off her eggs one day. I was lucky it was in the summer and that I had another clocker down. It was at least 5 hours be for I knew. I put them under the other clocker and luckily I had 2 hatch from the 6.
