I've read a lot of posts and took notes and I just finished the biggest part of my styrofoam cooler/incubator. I was worried about opening it and turning the eggs so I made a manual turner that allows me to turn the eggs from the outside. I'll only have to open to candle and then to take the chicks out You can't see from this picture but there is a tray of water in the back and I've got a straw leading to it so I can add more water easily. I've also got a mercury thermometer back there too. I have a small pane of glass from an old picture frame on the top and I can see everything from there. I hope it works! Here is the only picture I could upload with this poky connection... I've still got a little tweaking to do. I might try it out next week.
