Live Egg Candling (with follow up comments)

First, apologies for the video quality, apparently running Prism in 1080p isn't a good idea.
Second, the egg candler on this Nurture Right incubator is crap. If the housing was made of black ABS instead of white translucent plastic, then it might be a bit better. Also, the hole does not fit the large end of the egg, which is where you want the light to be.
After candling, I watched a dozen or so youtube videos and didn't see anything that looked like what I was seeing with the POS built in candler on the incubator.
So, I decided to use the best flashlight I had that I could press an egg against, the Olight mounted to my Girsan Regard, (see https://youtube.com/shorts/e2LfWZerS-E?feature=share )
With a proper light I could see thru the dark mass that I assumed was dead yolk and see veins and movement within the eggs.
After the re-candle, I tossed one egg that was not fertilized, and the other 10 look viable.
I've ordered a 'real' candle light from Amazon ( https://amzn.to/3YlD13S ) and will recheck the eggs when it arrives on Wednesday.
