There are 4 eggs that you can hear chirping from the inside, and several more that seem to be fertile when candled. One of the eggs had just hatched and we left it to dry off and do its thing, but when we returned we learned that the hen seemed to have accidentally crushed it. We got a styrofoam incubator but for now we are letting the hen sit on the rest of the eggs. Is it normal for little mishaps to happen like this? Is it too late to move the chicks to the incubator and is that wise or would the eggs likely be better off with the hen? And if they should be moved, what happens when they hatch in the incubator? I'm afraid if we move them and they hatch overnight that they will be left alone for hours in it. And to clarify, the temperature should be set between 99.5 - 102 degrees farenheit? Thank you!
