Yeah, I've got the incubator up and running and tubs ready minus water lol. I keep feeling like I'm gonna slide the tub one day and see eggs. The fact that she's consistently wide enough around to feel confident there could be full sized eggs inside her is making me go nuts.
Put water in the tubs now and place them in the incubator. You can add more water when you get some eggs. Put thermometers in the tubs while they are empty so you can test it out and adjust your t-stat temp.
