Ok lovely chicken friends (and other poultry folk as well)

. I need some advice.
My silkie eggs are now at day 11.
I went through quite an ordeal to get them. They were shipped across the pacific, so they went through an ordeal as well! Out of 16, 13 look great, beautiful veining and embryo movement. 2 have the saddles we discussed previously (sitting upright in cartons and hoping for the best) and one was infertile and I tossed it yesterday. My dilemma now is keeping the humidity down. My ambient humidity is 60% in the house. I do not have a dehumidifier. After reading the threads here, I have just placed a 1/4 cup charcoal in the incubator in a cup. I do not have any water added. The humidity in the incubator is running between 55-60%. have placed rice mixed with salt and baking soda in my other incubator that has marans eggs (day 10) in it, as they are suppose to run even drier. I will try the charcoal in there as well if the rice mixture does not work.
Attached photos of the pencil markings on the silkies between days 7 and 11. Most have almost no difference and a few have a slight difference. Any other ideas? I would hate for these little sweeties to drown! Thanks!
