Hi. I'm getting ready for my first hatch and I plan on incubating them in a carton. I was thinking of using one of my ceramic cartons since it can be sanitized and can act as a heat sink to help with keeping temps even. Will this work or will the eggs not get enough air? Should I switch to styro with holes poked in it (which would have to be bought with eggs in it and washed) or could I put half a cotton ball under each egg to help with the airflow?
