Yeah, also another thing to add. I know that everyone has their own way of incubation, but after reading the piece on dry incubation (something i am currently doing) I read that you don't open the incubator AT ALL from day 18 (after candling) till day 23!!! Your letting out precious humidity that is allowing the chicks to break free from their shell. Also, leave the chicks inside the incubator. They can stay inside without food or water for at least 48 hours.. My chicks (that are under a broody hen) have not eaten in 2 days!! They all stay under their mama and seem to be doing just fine, so with that being said you should leave all the chicks in the incubator UNTIL all of them hatch.. That way you get batter hatch results, and the chicks fluff out and have a better live expectancy. When i was raising quail i took a few wet babies out of the incubator (to join their siblings in the brooder) and i lost 2 of them. Now i wait, and wait, and ignore my impulses to help them out of the shell, cradle them, move them around, and just let nature take its course.. I have ALOT better results now... You may want to try a few things differently when you try again, just my 2 cents..
