Day 16 candle saxony egg :(

Not the best pics but I think my last egg has died
I've not seen movement at all whereas all the videos online show the embryo quite clearly moving by now.
There's no visible blood ring but the veins have gone dark,

Out of the other 3 eggs, 1 never developed, 1 stopped developing after a week and the other one seems to have stopped changing within the last few days.

It doesn't look good. If you don't see any movement, try the water method. Put one egg at a time in a bowl of warm water and see if there are any ripples (this indicates even the slightest movement in the egg)
