I would not give up hope. Keep going and candle in a few days to look for further development.
The reason you turn the eggs is that the yolk or embryo will settle and touch the sides of the shell. When it does that it sticks to the inside of the shell and dries out. If they stick that early I doubt they will survive hatching. Probably won't develop that far. And if they are stuck, they cannot rotate for hatching. If you do have some having trouble hatching, I would not help.
I have seen posts on here where people say the first few days are the most important for turning eggs. Until someone can explain why, I don't believe it. The chalaza are springs inside the egg that act as springs to keep the yolk and young developing embryo centered in the egg. The older the chalaza get, the more they stretch. The older the embryo gets the bigger it gets so it is closer to the egg shell and doesn't have as far to go to get stuck or dry out. I think the later in incubation you get the more important the turning is until you get to lockdown. Then the embryo is so big it is going to touch the sides no matter what you do so you quit turning and increase the humidity so it doesn't dry out.
The turner not working is not a good thing but I would not give up hope. Wish you luck!
