Pekin Duck egg/fertilization issue? How many eggs?

[christelbee]

This is our first year with poultry so I am a bit confused. If the egg has a red spot in it, that means it is fertilized, right? Or can they have the red spot without being fertilized. I have 2 Pekin ducks and we have been getting 2-3 eggs a day for the past couple of months. Usually 2, every few days it will be 3, and a couple of times we have had 4 eggs in one day. I was under the impression that both ducks were female, but the bigger one sometimes tries to mate on top of the smaller one. I thought maybe it was a dominance thing? But now we had a yolk with a red spot. Does that mean one is a male?

The red or 'blood' spot is evidence of a slight glitch in the egg production process. In commercial production such eggs are relegated to be used in baked goods. A fertilized egg will have a slightly enlarged bulls eye like blastocyst somewhat larger than the normal nucleus of the egg. If you are getting that many eggs in a day, you definitely have two hens.
