This is my first time hatching eggs from an incubator and candling chicken eggs. I know what to look out for but there is one egg out of the four that i'm worried about. The forth egg was developing fine until day 5 then it started not improving unlike the others who were developing well. Its now day 10 and the yolk moves around the egg instead of being in a fixed position when i candled it. I was going to throw it away today but i suddenly saw movement in the egg so i promptly placed it back in.
Do you think its still alive and whether its worth keeping?
Here is the egg: note it doesnt have any viens around the egg:
