Okay so this man gave my dad 12 eggs to try and hatch. Well supposely the man gave them to my dad around May 17. OK, so i know more about chickens then my dad does. But my dad left the 12 eggs in the egg carton sitting around in the house and he kept rotating the egg carton and would have one side higher then the other. He started turning them the day the man gave them to him. But i found out that the man had the eggs for about a week before he gave them to my dad is that okay?. So on May 19 or 20th, i candled the eggs, i know what im doing but i didn't see anything. Then on May 25 (yes a little bit late) i set the eggs in the incubator. I candled them again on June 3rd and 8 out of the 12 had great developing air sacs and a shadow in the egg. Then i examined their air sacs carefully and noticed they were a perfect circle and they were very smalll. So i am thinking these chicks are far along.But the main question is: When will they hatch? When should i stop turning them in the incubator? P.S. : Im 15, and not very good grammer, hopefully yall can understand this crazy story LOL:/ Thanks in advance.
