So, I have 3 call duck eggs on day 16 & 13 call duck eggs on day 5. How long to call ducks typically need to be incubated? This will be my first time hatching, raising, and owning call ducks, but I do own 21 other ducks so this is not brand new. I've read hatching other ducks is not that different from hatching calls except for the size difference and because call ducks have such short necks, bills they should be helped if there is no progress after the first 24hrs. Any advice would be great.
