OK lovely people I have a question for all of you experienced hatchers!

I have my six lonely eggs left out of 34 and they are supposed to hatch this weekend. I just weighed them all and plotted them out on my graph and they all seem to be a bit dry. I pulled the dry sponges a week ago, those are mostly for Marans and I only have one Marans egg left.
Dry incubating with a natural humidity between 35 and 45% right now. Question is should I add some water here the last few days or just let things be? Air cell sizes actually look OK, maybe a little big, hard to tell.
Thanks, I’m really hoping all six of these hatch! Good movement in all six of them. They are day 16 and a 17 right now.
