Can I replace the 'duds' under my broody hen after 1 week?

I tried moving the eggs. No success there. I did remove a barrier between 2 nesting boxes to give her food and water close by. On hatching day, I used a chicken wire door to keep the other hens out. On day 2, I moved mom and chicks to the back half of the coop and shut them off from the other hens. They are 2 weeks old now and she has them outside as often as I let her. I'll probably let her be outside at free will this weekend. The babies are so small and I'm trying to limit any predators access to them!

Mom will cover them should danger lurk.
