So my girl is due to lay next week (god I hope she doesn't go early and lay while I'm at NARBC this weekend!!). I got the incubator fired back up tonight (I did a test run when I 1st built it but turned it off till now) and I'm thinking I'll just set up the egg tub whenever I see eggs...unless ya'll think I should have that ready too? I'm planning to do the substrate-less method with vermiculite and a light diffuser. I'm using 6qt Sterilite tubs. How deep do you make the substrate? I was thinking somewhere around 1.5in? I actually have no frame of reference for how large bp eggs are and I'm worried if I make it too deep then I won't be able to fit the top on the tub. Am I being silly? Thanks guys!
