I did read your story ~ It made me go out and check the baby one more time. I was hoping to do some cpr to baby 4 but no luck - she is cold too. Still totally movable not stiff. Strange.
I am just going to move them out during the hatch itself I think. Since I don't have any way to keep them warm I figure that having Mama sit on them will be best. She doesn't display any interest in the eggs other than sitting on them. I will put in the water in the brooder - thank you I didn't think of that.
She seems to be a very good mom so far. When I watched the video it seemed like she moved the baby away from the group. She seems to be determined to hatch out all of the eggs.
