Finally! They're here! Seems like it took forever. This is my first ever attempt at hatching. I got 15 black sexlink eggs to incubate and hatch as my son's school science project (good excuse, right?). We are refrigerating 7 of the eggs and not 8 of them to compare hatch rates (to fufill his requirements for his project with a hypothesis and all that jazz). How long do you think they should stay in the fridge? I am thinking 4 hours? I am then planning on letting them get back to room temperature so they stand a chance. 8 hours to get back to room temp from the fridge, is that sufficient? I don't want to have to stay up all night to get them into the bator. One egg had a couple of hairline cracks. It's a goner isn't it? I used it as one of the fridge eggs. I'm nervous, never hatched before. I'm afraid of a total washout but I'm also nervous that I will have too many little chicks to rehome when all is said and done.
