Are my Ancona duck eggs fertile?

[SchCu18]

My male duck has been mating with two of my female ducks nearly everyday and I get two eggs a day, are they fertile? When will the female ducks start to brood?

Since they are domestic, I don't think there is a guarantee they will get broody. They might, though. Often, ducks wait till they have a nest full before they sit.

I would expect the eggs are fertile.

Why don't you crack one of the eggs open and see? Sometimes the eggs aren't fertile at first, even if they are mating daily. It took my guys a month or two to get it all worked out Google fertilized chicken egg and compare your eggs yolk to the images. It's pretty easy to figure out if you know what to look for.

If you want to try to hatch some, toss them in an incubator. If they're fertile in about a week you'll start to really see the development (at first it's just veining and a little heartbeat, pretty darn awesome) when you candle. I'm incubating 3 eggs right now for my neighbor (as a bonus, it's a science project for my son). Her male duck unfortunately died, so female is all alone right now. Hoping for at LEAST one successful hatch, last attempt (a couple months ago) with 3 eggs 1 infertile, 1 early death, other made development up to hatch but couldn't pip out. Unfortunately, last time was my first time, and I ran my humidity too high. This time I built an incubator. Today is only day 1, so we shall see.

I've had them in the incubator for a week now and they are all fertile, although one looks like it has stopped growing as it is smaller than the rest, so just going to see if it continues to grow
