How can you...?

[ChickenGal1842]

How can you tell when the eggs are going to hatch? I dont know how long the hen has been laying on them (vacation for 7 days) she might have been on for 5 days or something.... I know it takes about 20 days tho... I just want to be ready and know how to tell if they r about to hatch.

It usually takes 21 days for a baby chick to hatch. Raising Happy chickens has a day-by-day incubator process (with lots of pictures).
