I’m currently incubating 6 duck eggs, they are on day 21 today! I candled them yesterday and didn’t see one of them moving, I know movement and veining gets difficult to see at this stage, I checked on it again tonight and still can’t seem to see movement. I’m struggling to see veining, I think I can see some little ones but Im not sure the other are a lot stronger. I’m just unsure wether they are just disappearing or it’s just because it’s getting dark inside the egg. This egg is also smaller than the others and has a smaller air cell. Is there any way I can tell for definite that it’s dead as I’m scared to remove it just incase it isn’t.
