Eggs are kept almost like the adults are. Temps at 88-90.f also humidity needs to be at 90-100%. If you are going to leave the eggs with mom you will most likely have an issue keeping the humidity right. I have a rack and I still need to spray everyone down to keep up humidity. Mom could also have health issues because of staying coiled around her eggs like the above poster said. My opinion is to take the eggs and hatch them in an incubator. Any farm store has still air chicken incubators for 50.00 invest in that it will be the best for babies and mommy.
