I set some eggs on the 1st too in an old styrofoam hovabator.. This is my second attempt this year, my first try resulted in all the eggs quitting in their second week. My MIL sent a dozen eggs for me to try and hatch for her, and I bought some eggs from an Amish farm and put a couple of them in with the EE. No idea what kind of eggs they are, but my MIL won't know the difference, lol. Hopefully I can get something to hatch this time.
I'm doing several things differently. I added 1/4 cup water to a dish for humidity, and will add more on the 7th day, and if I still have viable eggs on the 14th day, I'll start raising the humidity. (I got this idea from EweSheep) I also have them in the center of the incubator in an egg carton that I'm tilting 30 degrees twice a day.
I hope this works. It seems like when I first bought my incubator, I just followed the instructions that came with it and had great hatches. Three years later, I started having trouble with soggy chicks and quitters. It's seven or eight years old now, and I haven't used it for a couple of years, except for the one time last month.
Wish me luck and if anyone has any tips, please let me know!
