Ok- latest hatch- set 27. Two were clears. Hatched 19. One died after zipping- I think the other chicks were too rough with him. Have four that look dead in shell. I am going to water candle and then do an egg-topsy if nothing shows living. I really, really love the huge window, but I have to say this isn't my favorite incubator. 19/25 is only 76%, not so great in my book for fresh eggs. I have had multiple chicks pip at the wrong end and part of all my hatches come a day early (the ones on the edges) which tells me the incubator is running HOT in those spots (confirmed by others in this thread). I had better rates with my old still air Little Giant. IDK. It's just not all that I expected. I'm happy to have the healthy 19 I got, but I would really have liked a few others to hatch as well. I built my own styrofoam chest bator with forced air, and I'm going to do a simulataneous hatch to see which performs best.
