I have decided to do a hatch for my 3rd grade class. It will be the first time ever so I am not sure how to do this. I want to be sure I have atleast some eggs hatch so the kids can see the process and are not dissapointed. I have decided on a hovobater 1588 I think it is genesis. What do I need to do? How can I be sure some chicks are growing? what is candeling and how exactly does it work? Is there anything else I need to know?
