I think everyone here was tryng to be very helpful and it was taken the wrong way.
It would be to any new chicken owner's benefit to get some books and read up on the care and other issues associated with having chickens full time.
You can eat any egg from most fowl - quail, chickens, turkeys, geese, ducks, emu, rhea, ostrich etc. You can eat them if they are fertile or infertile.
As the care giver of your own fowl you must check your nests daily, several times if you can, and collect your eggs and never leave them in the hen house.
You won't have any issues such as you described if you do this routinely, daily.
A fertile egg cannot develop into a chick with out being incubated either by a hen or by artificial means linke in a manmade incubator.
It takes 24 - 36 hours of incubation at 100 degrees for the embryo to begin developing. It won't happen sitting on your kitchen counter. It won't happen if you collect your eggs every day and put them in your refrigerator. A fertile egg has the potental to be a chick. It is not a chick waiting to spring forth from the shell.
If you do plan to continue to raise chickens or any other fowl that might catch your fancy I would heartly suggest that you get a back to basics type of how to and read, read, read. There are many books like Story's Guide to Raising Chickens/Poultry/etc that you would benefit from. Not only to learn the basics of poultry care and behavior to aid in the detection and need for medical intervention.
Welcome to BYC and enjoy your chickens.
