Does this look like normal development for duck eggs?
These are 2 of the 3 eggs that were put in the incubator the 20th,and are on day 5.


I couldn't get the pictures of the other 3 eggs to upload, but the other egg from the 20th looks about the same as the two above, and the two eggs set the 22nd have their first veins and, and their hearts are now visible!
