Hi - I am a chicken lover. I have 6 backyard hens... I am starting a chick hatching project in my daughter's classroom next week. I have a Little Giant circulated air incubator with an egg turner and I am getting 40 eggs from a friend with a farm full of roosters and hens. Does anyone have any advice for me before I begin? I really want this project to be successful. How likely is it that I will have chicks that do not hatch all the way? I do not mind if they do not hatch at all, but to hatch only part of the way upsets me. I was planning to start on a Tuesday around 2pm, so that they will hatch on a Monday or Tuesday. Thanks in advance for any advice.
