First time incubating quail eggs, need help!

1. It sounds like you have eggs that weren't shipped. Shipping decreases hatch rates because the eggs get rattled around and put through varying temps, x-rays, etc, so that can be a factor. Eggs also decrease in viability the older they are, and most keepers will tell you that eggs older than 10 days are unlikely to hatch.

2. It looks like this company sells different incubators. Here's the link to one that looked like it might be what you're using:

Cheaper incubators definitely work, but they can have...well, a lot more fluctuations. It's also recommended to get your own thermometer/hygrometer to double check because the built in ones aren't always reliable. At this point I'd probably consider getting a backup of some sort in case your incubator fails - otherwise, just keep a towel or Styrofoam around it and wait for day 10 to candle.

I am assuming your incubator also automatically turns the eggs? If not, you might need to do it yourself. Turning eggs, iirc, keeps the chick from getting stuck to a membrane? It's something hens do instinctively, anyway, and not turning the eggs can decrease the chances of an egg hatching.

Quail eggs should hatch within 17-18 days, but that time can change based on temp.

(As an aside, I follow a couple of quail groups and iirc saw the owner of Thieving Otter Farms show off a trick to candling quail eggs - take a laser pointer and light up the fat end of the egg. If it's developing, then you should see just the air bubble light up. If it's not, then the whole egg will light up because there's no chick to block the light. As a note, always keep the fat side up when candling to avoid messing with the air bubble.)

Hello,
It is day 19 and none of the eggs have hatched. I few that we took out earlier seemed to be cooked. Are all of them lost? What happened that the incubator cooked the eggs?

Did you have a calibrated thermometer or three in there? Incubators are very rarely accurate in their readings.

Cooked? As in steamed? What did the eggs look like when you candled?

We had an additional thermometer in. The ones that showed nothing inside, no red or growth, we cracked and seem to be hard boiled. No completely just some.

Wow. You mentioned temperature fluctuations, but that is extreme. Temperature fluctuations are the hardest to get good results with. If your temp is a bit high or a bit low, but generally constant you have a higher chance of hatch.

I would spend a bit more for a better incubator next time.
