The cause of missing eyes can be either high incubator temperature or low oxygen some time from day 1 thru 6 of incubation - or both.
Wow!!!!! 163!!! How gorgeous. Would love to see a pic.
We had two hatch last year that were one eyed monsters. Missing eye on one side like yours and the other side had a massive bulging eye. They also had bad cross beaks. Ended up culling them as they couldn't eat or drink on their own. After 3 days of hand feeding with no improvement in independence we decided to cull.
Thanks for the pics. How gorgeous they all are. Most we have ever had at one time has been 17 quail and 17 chickens, not at the same time though. We only have a small incubator though, which only fits 24 chicken eggs and supposedly 60-70 quail eggs, but it didn't come with enough dividers to fit that many quail eggs in order to allow for the rolling. Have had up to 56 quail eggs in there though, but had a very poor hatch rate as they were shipped eggs and a lot weren't even fertile.
