I found this on another BYCer's page. If/when you are able to get some, just PM me. I can come pick them up. THANK YOU!!!
Try to gather the eggs as soon as possible after they are laid. Two to three times per day if possible in extreme weather. Eggs need to be keep above 50 and below 70 degrees until incubated. Below 50 degrees the embryo is at risk of dying. Above 70 and the embryo begins to develop and then dies if proper incubating temperatures are not maintained. During cold weather you have the risk of freezing or getting cold enough to kill the embryo. During warm weather you have a risk of them getting to warm. “DO NOT REFRIGERATE”!
Gather eggs in a clean container with clean hands. The less you handle the eggs the better they are. Be gentle with them to avoid cracking.
“Never Wash The Eggs”! If they are soiled badly wipe gently with a dry paper towel or reject it for incubating. Washing with water can push bacteria through the natural protective coating of the egg. Check eggs rejecting any that have cracks or other defects. Deformed or odd shaped eggs rarely hatch!
If you would like to mark the egg with breed or date collected it should be done with a #2 pencil. Never use a magic or permanent marker! Some ink pens can also be damaging to the embryo.
Place eggs in a clean Cardboard or Styrofoam egg carton. “Large End Up” pointy tip down into carton! Store the eggs in a cool place such as a basement, garage or area that will stay between 60 and 65 degrees. Elevate one end of the egg carton on a large book or even another egg carton and alternate which end is tipped a couple of times a day, that is recommended, to keep the yolk from settling on one side or the other. This exercises the embryo and prevents it from sticking inside the shell. This guy uses a Wine Cooler set between 64 to 65 degrees to store eggs in.
Chicken eggs can be saved for a week to ten days and sometimes more. Incubate eggs that are no more than 7 to 10 days old. After 10 days the hatch rate drops rapidly.
As for transportation, always do it very carefully. Wrap the carton(s) in a towel for padding, then place them in the car where they are least likely to move around. Avoid hitting pot holes while going fast and generally accelerate and brake a little more slowly and carefully. I don't know if any of that makes a difference but I figure the main problem with shipped eggs is the treatment they get in transit so I try to make eggs I've picked up have as smooth a journey as possible.
