My bators are in my store room at school. They stay more consistently warm there than at home. Today is the day for my first 15. I have one that has zipped about 1/3 of the shell and no activity in the others. Since i was not here, I don't know when Norbert started working. I hear an occasional chirp. I am hopeful for a good hatch. The EEs are due to hatch next Friday. Candling indicates quick development so they may be a bit early.
