I have two hens laying on about 30 eggs. Tomorrow is day 21 for about 13 of them. This morning the girls got off the nest to get a drink and eat, and of course I high-tailed it to the coop to take a peek ...There is one egg that has a nickel size hole in the egg but the membrane is still covering the chick...and 4 other eggs have pip marks...I am so excited!!! Question #1 How long will it be before they actually break out? Question #2 Should I take the chicks from the Momma(s) at night??
