I believe one of my duckies is about to hatch. First time I've ever incubated duck eggs. The air pocket has gotten pretty big but I read that you should hear them making noise just before hatching?? It's day 25 or 26 so I know the little guy is about ready to leave his shell. Anyway I guess I'm hung up on the noise thing, as I don't know if: A) That's always the case B) Does it mean they're not healthy if you don't hear little chirps? Like I said I'm new to this, so forgive me if I sound ignorant. Thanks for any help.
