I’m very sorry about the chick. I would recommend making the room darker and using a stronger light. The lights on incubators typically aren’t great and often don’t show early development as clearly.
What day of incubation is it? You won’t usually be able to see obvious signs of development by candling for several days.
I’m no expert on candling, but I do see a bit of a darker spot at the top of the egg in the first picture. It could just be a shadow but I’m not sure. Also, the fat end of the egg contains the air cell, and shining the light through it may negatively affect the visibility in the egg. It is recommended that you shine the light through the side or small end of the egg to see everything inside as clearly as possible, as well as ensure the chick’s safety because its head will develop in the fat end near the air cell.
I always leave all of my eggs in the incubator until a few days before the hatch, just in case I missed something when candling.
Best of luck, and I hope you get a good hatch!
