incubating duck eggs

[KittyUK]

I taped my chicks legs and it worked! It had one leg facing backward and it's foot wasn't working. Taped it with a band aid and everything straightened out, even it's bent toe. Magical.

I'm hatching duck eggs in a month so I'll be back here soon having a panic, no doubt!

I have a 29 eggs in my still air incubator.
Temperature is 100
Humidity is 65

The way it's set up I have a turner in it and room for about 12 eggs to pip.

Currently, I have 4 that are due to pip sometime. Problem is when I candle them Wednesday and I can't see anything but black. Can see very little movement inside.
When they sit they do the shaking thing.

I put them on lockdown on Wednesday because some sites say it wont be long after they start shaking. Is it to early?
When we put these 4 in we didn't date them so we are flying blind to the day they may hatch.
