This may be a silly question but here it goes... When you have both male and female ducks...can you still eat the eggs??
A fertilized egg does not develop unless you put it into incubation with 100 degree for 4 days. Before that it is identical to unfertilized eggs. You put it into the fridge and it will never develop and you can store it just like all other eggs for up to 6 weeks. You can store it longer, but they are just not getting fresher and the air sack just gets larger. For taste. No difference what so ever.
