I got some duck eggs and put them in the incubator 27 days ago. One of the eggs had a whole in it about 2 days ago, the egg is slightly shaking and you can just see the duck through the whole and it is chirping. I am not sure if the duck is stuck as it whole has not got much bigger. The two other eggs i got are fertile but not showing any signs of hatching. Do you know if the duckling is stuck, and if so what can i do to keep it alive.
