Black spot on duck egg in incubator

[Scornwell]

Hello there: my duck eggs are due to hatch today . Two have pipped and are starting to zip but there are a couple that have these black spots that are growing. I am so worried. They have not pipped. Does anyone know what this means. He black spots are on the outside of the shell not inside. I have not opened or candled since lockdown. I have been looking all over this awesome site for similar issues. Please let me know if you know anything about this. Do they need help? Are they dead I will post a picture.

Hello there and welcome to BYC!

I have never hatched duck eggs. You might want to post this in our Ducks section to chat with all those Duck experts on this....https://www.backyardchickens.com/f/42/ducks

Good luck with your hatch.

Welcome to BYC!

We're glad to have you.

I haven't incubated duck eggs before. In my chicken eggs, I don't believe I've seen exactly what you're experiencing. However, I do know that, in the past, some of my chicken eggs that I stored before incubation did develop small black or grey flecks. In my case, it turned out to be spots of mold. I was keeping them too damp. I ended up not incubating those eggs, so I don't know whether they would have hatched or not.

Glad you joined us!

X2 on Wyandottes7. My best guess is that your black spots are some sort of mold.

I'm guessing mold as well
