I still have 4 eggs in my lg bator that haven't hatched. I put them in March 16th at 5pm. So I counted 17th as day 1. Friday (april 6th) was day 21. Two eggs started to hatch thursday and hatched out friday early morning. Then one more hatched out at midnight saturday. Nothing since. so i guess today at 5pm will be day 24! I candled them today and there was no movement. So i cracked them open and all 4 were fully developed chicks! WHy didn't they hatch? I know there are a million reasons....i just makes me so mad they made it that far and then did't hatch.
