Thank you! Do you have a tip on what kind of light to use for candling dark eggs? I can't even see which end the air pocket is on. They are so dark.
That's great they are too dark to candle.. thats what we want! Lol I usually dont even really bother candling Marans eggs until I put them into lockdown on the 18th day. At thay point, eggs with development will have a distinct lighter colored air cell and below it will be very dark because at that point most of the egg is occupied by the chick.
Here is an egg on the 11th day of incubation. The color is about a 5 but all you can really see is the distinct color difference of the air cell and the part below it with the developing chick. Thats all I really look for because that shows the egg is developing. I use an inexpensive LED flashlight from Walmart. It is Ozark Trail brand. It is pretty bright and its the best flashlight Ive ever used for candling.
