Longest time it takes to hatch?

[ldrchickens]

Hey guys! So through the night I had 9 babies hatch. 7 quail and 2 chickens. I have a couple more eggs pipped and there are a lot more with nothing. Is this normal? How long can it take to complete a hatch? There original due date is Saturday but i think i miscalculated on the quail and put them in early. Is it possible the chickens are not quit ready but just hatched because they heard the others? How long should I wait to call it quits? 3 days?

Candle the eggs. Hatch time varies with specie and environmental factors. Genetics can also play a part in how long or if the egg hatches.
