Are these eggs fertilized

[JonathanL23]

So i have a male who is mating 3 female ducks i know one for sure, when i go out in the morning to check for chicken eggs theres always a duck egg on the floor im guessing she not ready or smart enough yet to make a nest. so instead of letting the egg go to waste i feed it to a dog , but i always look at it first and the last few times ill notice even with a few chicken eggs theres a white spot in the middle of the yolk does this mean its fertilized.

There is always a white spot regardless. It is called the blastodisc. If it is shaped like a bulls eye the egg is fertile. You can google photos to see what it looks like.

Most ducks don't use nesting boxes and unless the duck is going broody she won't make a nest, so to speak. Pics of the eggs would be helpful but you are looking for a bullseye.
