In some places it is quite normal to store eggs in the refrigerator while in others, keeping eggs out in room temperature is the norm. They probably keep longer in the fridge, though.
Store at room temperature, pointy end down in egg cartons, until you have collected the number of eggs you want to incubate.
Fridge
If you are collecting the fertile eggs (the eggs from stores are infertile) store them upside down in an egg cartoon in a cool place (NOT THE FRIDGE). Don't let them sit for more than one week. Once you either have all you want or it has been a week you may now place them in an incubator or under a broody hen.
You can build your own incubator but if you want a manufactured one, you can get them at any country feen store locally. Places like Co-Op, Agri store or even order them on the internet.
It is not necessary to store sodium chloride in an incubator. For laboratory use dried NaCl must be stored in an exsiccator.
Commercial chicken eggs you buy in the store are laid by hens that have no contact with roosters, therefore, you won't be able to hatch anything from them. Also, the fertile egg is only good for about 17 days. If it's not warmed by a hen or an incubator within that time, chances are that it's not viable.
Store them in a cool dry place, like a cupboard or dresser drawer. Do not store them in the bathroom where damage from moisture could make them less effective.
Well, i know you can find it before, have you checked in the department store and the poketch place?
Hectic means busy, intense agitation, excitement, confused. A hectic place would be a shopping center before a major holiday or the grocery store before a major holiday.
You really do not want keep them more than 5 days without incubation, after that they become weak and the chances of them hatching goes down by the day. Keep fertile eggs in a cool-humid storage area. Ideal storage conditions include a 55 degree F. temperature and 75% relative humidity. Store the eggs with the small end pointed downward. Alter egg position periodically if not incubating within 4-7 days. Turn the eggs to a new position once daily until placing in the incubator. Hatchability holds well up to seven days, but declines rapidly after that. Try not to store eggs more than 7 days before incubating. A 14 day storage reduces hatch to near 50% and after 3 weeks of storage, hatchability drops to almost zero. Plan ahead and have a regular hatching schedule to avoid storage problems and reduced hatch percentages. Allow cool eggs to warm slowly to room temperature before placing in the incubator. Abrupt warming from 55 degrees to 100 degrees causes moisture condensation on the egg shell that leads to disease and reduced hatches. Start incubator 24 hrs ahead of loading to fine tune temperature and humidity settings. Dirty eggs should not be saved.Slightly soiled eggs are fine. Do not wash dirty eggs. Removing the bloom triples the chance of sick,deformed chicks. Of those that do survive the hatch, mortality is high the first week.
Most store bought eggs come from hens not socialized with roosters, therefore they cannot be fertile. If you mean somehow fertilizing them after purchase, no. Fertilization happens inside the hen during mating. The shell is then formed around the yolk and white, and is then laid by the hen. Once the shell is formed, it is too late for it to be fertilized.
Store eggs in cold, dry place and do not wash it before storing
The best way is to get a small incubator from the local feed store. a three egg incubator is less than $50.00 and will produce the best results. Next best thing is find a broody hen and let her sit on the egg.
Chicken eggs from the store will NOT hatch no matter what you do to them. By the time they get to the store they have been away from the warmth of the mother, or any kind of warmth, for far too long to be fertile.
