What temperature are they at? It sounds like the temperature is a bit low. Don't trust the incubator thermometer.Second hatch in a row, quail didn't begin hatching until day 19. Originally set 107 eggs, 97 fertile and as of last night I moved 20 to brooder and 5 new still hatching or still wet in hatching trays. For a temporary current hatch rate of 23% and 26% of fertile hatched. I'm expecting a whole lot more to be hatched when I get home from work in a couple of hours.
