Egg day 17 of 21

... This egg is day 17 of 21 and this picture of me candling it is horrible, but you can't see through the egg at all and it looks like something is in there. Could this egg potentially hatch?

I can't really say from that pic. At this stage you should be able to see quite a bit of development, the embryo and some veins, especially just below the air cell. Here are some egg candling pics you can use as reference:

Try shining the light down through the air cell. I may have a pic of me candling in my photo album for an example. Watch for movement and look for veins. Mostly up by the air cell if the egg is mostly dark and almost through incubation.
