Ok, this is our first time hatching eggs. Our Brooding Hen was sitting on 18 eggs before we figured out to separate the other two hens away from her. It's been 22 days since we did, she couldn't keep one chick alive so we brought three inside to take care of and we put seven of her eleven eggs left in the incubator. Four chicks didn't make it, then she stopped brooding and left four eggs unhatched. Our incubator only holds seven eggs. They started hatching last Sunday, one hatched every day for five days. Out of the two left, one is chirping but not trying to peck its way out. We don't hear anything from the other one. We thought maybe the shell might be too thick for it to peck out? They are Blue Splash Marans and the darkest egg's shells are really hard. It takes a lot of force just to bust one open to fry. Should we try to help it get out or just wait to see what happens? This was the darkest brown egg out of the bunch. All we know is the egg has to be 22 days old or older. And the poor little thing is chirping like it wants out! It's been chirping for 24 hours now.
