Chicken eggs take 21 days to hatch, and quail eggs take 17 days to hatch so it's important to know the exact day you put them in the incubator. I maintain the temp. 37.6 C and humidity 60 % and increase it to 65% at hatching time for fully emerge from its shell.
If some of the chicks haven't concluded their hatching after twelve hours, go ahead and remove the tops of those eggs. Thank you for watching and subscribe .
