If on the other hand you use an incubator in order to hatch fertilized chicken eggs, they can sometimes hatch a day or two early, or they can also hatch out a few days late. Things like humidity and temperature play a significant role.
show more my eggs are due to hatch in 4 days. do i leave them in incubator after they hatch or do i tensfer them to a brooder straight away. This is my 2nd attempt at hatching duck eggs as i had no joy on 1st try as they died on day 24 due to temp changes suddenly.I have now got a better incubator and so far all seem...ransfer them into the brooder, with heat lamp, within 12 hours of hatching. When they are 2 weeks old, start decreasing the bulb temp gradually every day, until they are 4 weeks old. Then, they will no longer need to be incubated.
