Between what you already had planned and what Oz has said I think you have a good plan. I would also dry as much water out as possible until you get a hygro and start candling and checking air cells. Keeping in egg cartons is a good idea since you are going to have such a crazy hatch. Turning early is really important. Twist up a paper towel and stuff an end thru the wire and let it wick up water for you. After that the heat will dry it out pretty quick. Good luck and keep us updated.
I picked up a cheap one at walmart and will set up when I get home and dry out the bator. What I'll do is put them on top of the heating pad(that heats my box bator) and drain it and wipe it dry. I'll then very slowly add water if I need to (only if the humidity drops below 20%. I will try to remember to update here but I will deff be updating my thread. And I am monitering cell size. I'm gonna trace them when I get home. Well as best as I can...
