Quail eggs stopped developing, what could be wrong?

[BookThief]

My partner and I got 12 quail eggs to hatch, and 6 chicken eggs. Of the quail eggs, all but 1 began to develop, then they all stopped. They haven't been growing for a while, then we realized they had all died. The chicken eggs are still doing perfectly fine, with no issue. We have the chicken eggs and the quail eggs separated, and the temperature for both is pretty stable. Has anyone had something similar to happen? Or would anyone might know what went wrong, so it doesn't happen again?

Are the quail eggs yours or did you buy them?

We bought them from someone who regularly sales fertile eggs

Eggs that start then stop happen all the time no matter the species of bird. It could be a few things. Early death can be poor care of the adults, in breeding of the adults where certain lines are not strong. Your incubator could also play a role. There will always be dead spots in incubators where heat isn't the strongest. I raised quail and I found that fancy colors like silvers never reproduced well. I love the color but they were hard to hatch for me. And never could I hatch the blue eggs. Although pretty, when you breed only for color of either the bird or eggs, other parts of the bird suffers like vitality. Even though people sell alot of birds doesn't mean what they breed is strong and healthy.
If your going to set your own eggs, you must have tough skin so look around and buy more eggs. I've set hundreds of eggs. I've had some great hatches and this year I've had dismal hatches. We are talking coturnix right?

Yes, they are corturnix. And that makes complete sense. Thank you for your reply. I actually bought 12, and none developed at all. Figured I did something wrong, so bought another 12 and this happened. About half the eggs of both clutches were blue. I ended up just getting some chicks, rather then trying to hatch them. But that's good to know for the future, thank you.
