I am a newbie to hatching. I have 12 eggs in an incubator at school in my classroom. The incubator didn't have instructions. And today was day 21. Here is what I am not sure about.... did I need to lay the eggs on their side in the bottom of the incubator? What I did was cut apart an egg carton and put the eggs in the "cups" with the big end up on Tuesday. I didn't cut the bottoms out. The egg carton is styrofoam. There doesn't seem to be any activity yet. Should the temp be different now? It is a still air incubator and from what I have read the temp needed to be at 102. It has been very consistant and I have kept water in there also. I am afraid I have candled them too many times. BUT from candling, I do know that 2 of them were not fertile. I am more anxious than the kids are! I am just afraid that none of them are going to hatch.
