Question about egg boxes

[Bill Buchman]

I use substrateless with 6 qrt. I split larger clutches in 2 boxes. I use perlite with Press and Seal, 1/2 cup water with 2 inches of substrate. I don't open the box until day 45-47. I then take off Press and Seal to allow for heat generation and oxygen transfer -- and put the lid back on. Works like a charm and no stress. Good luck!
