Setting eggs means putting them in an incubator or under a broody hen, but usually if you say setting, you mean a bator. You collect the eggs and store them in a cool place, not the fridge, large end with the air cell upwards, for up to two weeks, preferably only one week, then you put them in the bator. You turn the eggs, but not end to end, usually you tilt them slightly side to side so the yolk won't stick to one side of the egg. I store the eggs in an egg flat in my bsmt, which stays around 55 degrees in the summer and 45 degrees in the winter will I put them in the bator. Hope this clears some of it up for you!
