fertile eggs????

[chrisarvor]

I have had my Muscovy ducks for a while and now they are laying
i eat most of the eggs at the moment but when i break them open i am not sure if they are fertile???
my chicken eggs always have a tail attached to the yolk sack but the ducks dont seem to have this
Should they be the same as the chickens ??

I would think it would be very similar to chicken eggs when determining if fertile or not.

Tails attached to the egg is not a sign of fertility. The bullseye in the yolk is often a visual clue of fertile eggs.
