When should they start to move around?

[Jaguar6]

Hello,

I am waiting and waiting for the chicks to start moving around in their eggs. They are at day 20, should I have seen them roll around yet? This is my first hatch and I have had temp and humidity issues in our homemade styrofoam cooler incubater. I had 2 eggs with nothing in them when I candled and 1 rotten egg that I just threw out. Now I am hoping for at least half of them to hatch, especially my blue cochin. Please let me know if this is normal or not.

Keep waiting. You should see something around day 21.
