At the moment I have moved the incubator to my room and i put it in a Styrofoam box as i was concerned the box it came in want allowing enough air to circulate, but it makes it so big. Will it be safe to put it in the cardboard box it came in with the foam surrounding it or will it not allow enough air to circulate when I have eggs in it? The instructions say to use the packaging box and foam but as you can see with the picture below it doesn't exactly allow much air around and at night I have to close it up with a book on it (to keep t closed) to keep the temperature at 47.5C.
