Here’s a cut down carton from last year. You could cut it more than I did even, I think my hand was just getting tired since this was my big hatch last year, but they were fine. I believe this carton had the taller parts in the middle so I cut those off. I have used the styrofoam ones also, those have less of that so I didn’t cut them as much. But I used them from start to finish before I had an egg turner. I would just put a small book under one end and switch it several times a day.
