what i did with mine as this is her first hatch, i put some in the incubator and left her with 4 eggs, so if they don't hatch i will have some babies to put under her on the day of their hatching, so she will have some babies to care for. the only trouble is i only thought of doing this when she was sat on eggs on day 4 so there will be a time difference so i am hoping that if i slip these babies in at night she will except them.
