I own three hens and a drake. I have decided to try and hatch out a clutch of eggs. My issue is how do you tell which eggs have been fertilized and which ones haven't. My duck hens have been laying three-four eggs a day the last four days. Today I only found two eggs and its very obvious that they are not fertile but they might be. Is there a way to tell if the drake got to them?
You can crack some open for breakfast. The way people here have discovered how to tell a fertile egg from a non fertile, is by looking at certain spot on the yolk. There should be a white dot on every yolk. If the dot is surrounded by a ring, it is fertile. It is described as looking like a bull's eye. This is known as the Blastoderm, and is also refereed to as the germinal disc, and means the egg is fertile. i would just eat the eggs everyday, until you start seeing the bulls eye, then after you know thy are laying fertile eggs, start saving them. I don't think there is any other way to tell if an eggs is fertile or not unless you crack it open using this method, or incubate it for a time.
