Very good.sooo true.....................The movement you see if the chick getting in position to hatch. They will move, wiggle till they are comfortable. Some dont move at all, they are happy with the position they are in. Then the chick will get very quiet. I wait till day 23 before I do anything. Then candle and do a float test. These last days are the hardest. You need 3 things when hatching. A friend, chair and rope. The friend to tie you to the chair with the rope! LOL Just let it do it's thing!
