I'll typically crack open an egg, hold it slightly open over the pan to precook that watery part first before dumping the rest of the egg in an effort to get a little better shape. Oddly enough, that doesn't work too great.

Candling is for detecting excessive blood spots, if the egg is
fertilized, and to check fertilized egg development in the incubators.
Today candling is done electronically, with high intensity LED light,
with computerized/digitized imaging, and at high speed as the eggs
pass the candling device on conveyer belts. Computer programs check
images for grading. If eggs were individually graded by humans the
old fashioned way eggs would be too expensive. And not just chicken
eggs are candled, all poultry eggs are candled... the turkey farmer
can't afford a dead egg in the incubator, or it will probably explode
and ruin maybe a thousand fertilized developing eggs... fertilized
eggs are candled often as they mature. If turkey farmers used old
fashioned methods few of us could afford a Thanksgiving turkey... it
would cost less to hunt wild turkey and for those without access to
land with wild turkeys hunting the family bird can be prohibitively
expensive. Plenty wild turkey here but no hunting allowed:
