So sorry about your hatch. It is heartbreaking when something like that happens. I agree about the humidity being high. I try to keeo mine close to 50% for the first 18 days,in fact,I don't even add water unless it has been down to 49% for a day or more.Don't get discouraged.My first hatch was 0%. I was using an old Brower and never could get the temps to stabalize. Next time I bought a new wafer thermastat and had a great hatch.
