Let me know what you decide about the carton vs floor, I am a first timer struggling with that decision too. Thanks.
Jane Marie- good luck and post pics!!! I had been worried about my humidity not stay in the 40s but now I am deciding that I am not adding water unless it gets below 25. I had them at 39 last night and didn't add water and this morning it went up to 44 on it's own, I think the eggs are finally losing some of their weight so I'm not adding anymore. I even took a sponge OUT today and it's still fine. I wish I would have done dry hatch from the start of this one! Glad to see so many support it!
