This is my fifth hatch and my last two didn't go so well. We are on day 20 and one egg was rocking this morning and early afternoon. With my other hatches I never noticed the rocking so I have no idea how long it can go on for. Can they rock around for a day? Honestly my last two hatches yielded 0 chicks so I am in panic mode. I did only put a few eggs in each time, but still that is pathetic. I am so paranoid I am going to lose the one chick that I know is alive in there. I candled all five of the eggs a couple of days ago so I know they are fully developed.
