Can you candle coturnix eggs?

I'm incubating some grocery store eggs...I'm candling every day. I know this is not ideal, but it is good education for the children and we try to take no longer than 2-3 minutes a day of the egg out of the 'bator.

Anyway, it's been so enjoyable to watch these babies GROW GROW GROW! I'm wondering, as my next batch in the bator will be coturnix, if their shells are candleable?

I'm so excited! I've ordered 2 dozen fertile eggs from a local breeder and I get them August 20.

Thanks!

Yes and no. Most of them are too dark to see any veining. I have been able to see just before setting to hatch, whether or not its grown or not (dark vs. light). But it isn't perfect. I still had many that weren't viable go to the last day of incubation. But those I have disposed of I have been right on with. It isn't at all like chicken eggs.
 
You probably can't see veining (unless you have a super bright light), but you should be able to tell if it is developing. By day 10-ish, the lower half (at least) of the egg will be completely dark. Some eggs are impossible to see through, especially if they have a darker shell. But you should be able to tell by day 10-14 if the eggs are clear or not.

Yes and no. If i incubate my Quail eggs i tend to use the ones that don't have that many spots or dark splotches. Mainly what i see is at day 3-7 you can see red. And if you have the really dark eggs with alot of spots then you might not be able to see them as much.
 
Coturinx eggs are not the best to study embryo development by candling. You have to break the shell in most cases.
I candle at around 7-8 days. Anything glowing like a Christmas tree is disguarded as a yolker, any muddy,red,pink I see means a viable egg.
I candle again at day 14, before I seal the bator, bump up the humidity to 70%+ and await for hatch 4 days later. All rules apply here, but I don't disguard any eggs.
 
Thank you for all the responses!

I'm glad that we're having such fun with the chicken eggs then, as it sounds like the only thing we'll be able to do is check viability rather than watch them grow.

Thanks again...you folks have been nothing but helpful to me.

I can`t see a thing in coturnix eggs, not like I can in bobwhites. I use a small glass of lukewarm water at around day 10. Put your egg into the water and if it starts to wiggle you got a live one in there. It only takes a second to see any movement, don`t leave em in there too long though. about 15 seconds is all it takes. Good Luck
