Egg hatching issues

[crazy rooster34]

So i started incubating my NH x SS eggs and when i candled them i saw no veins on any of them so i cracked one open and sure enough a embryo was inside so i put all 12 eggs back in, but did i disturb the eggs to much to the point of them not hatching i placed them all down and then had to transfer them back to the incubator , I'm worried i disturbed them to much , and why couldn't i see the veins when candling

How many days have they been in the incubator? You shouldn't candle the eggs before day 7, as then you can really see what's going on in the eggs. It takes a few days to start seeing veins etc.

Don't worry, eggs are surprisingly durable. You haven't ruined their chance of hatching. I would just keep candling to a minimum and let them do their thing.

Also brown eggs are harder to see what is going on until they are at least seven days if not more. I did the same thing with a seven day old egg that was under a broody.

I agree with what was said above. Also, if they were farther along and you still couldn't see in them, your candler is probably too weak. With a good candler, it's possible to see development in an egg as early as 3 or 4 days. You might want to buy a small strong flashlight that has the highest amount of lumens you can find. My candler is about 200 or so and can see into even dark eggs.

The eggs are probably fine and will still hatch. Moving them out of the incubator shouldn't have hurt them unless you really shook them around.
