Shoot, I forgot sponges at the store today

I knew I was missing something.
I feel I should clarify that I want to hatch on the drier side because I don't enjoy the anxiety of always fiddling with the humidity, and one of my incubators seems to WANT to run dry lol. Either that or way too humid, and I would like to avoid drowning anybody. It's not necessarily because that's how other people do it or it is popular on this thread. I feel like my first hatch went relatively well, but I was fiddling with the humidity a LOT trying to keep it acceptable. My next chicken hatch is with eggs from my own flock, so they will be easy to replace if I go too dry or too humid and they don't make it. My main interest is finding a method that works well for me in this climate.
I love your thread idea, FortCluck! Please tag me in it. I'm going to be keeping track of this next hatch and all upcoming hatches in a spreadsheet anyway, so I'd love to be able to compare data/results with people.
