Friday (day 7) marked the end of week one of incubation. Eggs can be candled (use of a bright light to see the contents of an egg) around day 7 to determine fertility and the rate at which they are dehydrating. I am happy to announce that all six of my duck eggs are fertile and progressing nicely! Below is one of my eggs being candled on a flashlight and toilet paper tube, my DIY egg candler. The green arrow is identifying the air cell which is used to determine whether the egg is dehydrating correctly. You can see where I drew a dotted outline of the air cell (below) for comparison at the next candling. The dates on the eggs reflect when the breeder collected the eggs. The blue arrow identifies the "eye" of the embryo and what will eventually be a duckling! Finally, the pink arrows are pointing out developing blood vessels, nourishing the embryo. Week two will constitute an increase in incubator temperature to 102 degrees and a seven minute cooling period & light spraying of water each day.
