Half of the egg is dark at day 4-5 ish??

[Evelynn Averia]

We're really curious about this but its a bit hard to explain, so our eggs is on day 4-5 ish of incubation, we candled some of them and one of the eggs was really dark at the top (nearly half of the egg was dark) and there was a little bit of movement. Its very different compared to the others, it has some veins but theres no way a chick can grow this much in 4-5 days! Any ideas on what this means?
- I got no pictures of it, forgot to take one.

Could you try using a brighter light for candling? Personally my incubator's built in light is pretty dim, and my phone torch is brighter. Maybe you could use your phone torch and see if you can get a better look inside? make sure the room is very dark too. I'm wondering if the shells are simply thick.
Are you seeing veins in person? It's a little hard to see properly in the photos. And is there any chance that the eggs started to develop before you collected them? Or were these shipped/bought?

Hi, sorry for late response. We can't candle them here at the second because I aint where the incubator are. The eggs were shipped to us and took about a week before they arrived, they may have developed before they collected them but I'm not sure. We're stressed because we don't know which day they are on, and why they are so dark.

Next time you candle them, I suggest you move the egg around and shine the light from several different parts (the bottom, one side, another side, the small end, etc.)

I have seen eggs that looked dark like yours when the light just wasn't strong enough to light up the whole egg. Moving the light or the egg let me see that each part of the egg looked normal when it was close enough to the light. (The second egg especially looks like what mine did; I think the first one looks different.)

I don't know if this is what is happening with your eggs, but it's fairly easy to check next time you candle.
