I am so sorry too.
I remember my first hatch and it failed from low temps and how I sat around and cried because I felt like such a failure to the poor little ones. Then determination set in and I was set to figure out how to hatch once and for all. Well, let's just say I hatch more than I can brood here sometimes. Don't give up and keep trying. Once you get it, you're set. And please don't blame yourself..this is all a learning process and even first time mother hens don't get it right the first time. Let us know how the next hatch goes.
