Today is day 25 so far I've gotten 6 nice fluffy chicks out of 14 eggs I set on the 31st of Dec. I cleaned out the bator and broke open the 8 eggs that were left. What I found was 5 duds that never did anything, 2 partial chicks that looked like they had gone quite some time before something happened, and 1 fully developed chick that looked like he was ready to come out, but something happened. Oh well. When I locked them down I had temp and humidity swings that you wouldn't believe. Temps to 104,Humidity at 99.9, I messed with everything and had at one point given up, and let them go to see what would happen. I got 6 so something went right.Good Luck to everyone that's set or is setting eggs, nothing says they will or won't hatch, you can have the best incubator or the cheapest like I had, and you get what you get. Keep trying, I'm going to, but I'm making a different bator than the last one.
