The mother duck was sitting on the duck eggs for 2 weeks and the have been with us for about 3 weeks and we dont have an incubator but when we candle them we see the air cell and a little dark figure and I'm not sure if they are moving and I'm having a hard time trying to convince people to wait to see if they hatch and I'm starting to think they wont I'm worried that they are dead and I would really appreciate any advice on what to do with the eggs thankyou
