Leave the chicks with mom, and give her another day or 2. Hopefully she will continue to tend the eggs at least a few more days. But she will need to teach the babies to forge and find water soon. Moving all the eggs and new chicks to a ground nest will help for a few days, and hopefully get a few more chicks. But eventually the hen will leave the nest to tend the babies. She may need to pick up an incubator or let the other unhatched eggs go to waste.
Perhaps a box that she can put feed and water in for mom and the chicks would help with the move. She needs to be prepared for mom to abandon the eggs.
I would think the nest should be moved soon so babies don't fall of the edge, or at least a 3-4in board placed in front for the day, and try to move the nest at night
