Do ducks hear sounds inside the egg?

[Paterino Del Galaxia]

So as you know i am incubating a muscovy duck egg, it is now on day 26 to 27. So do ducks hear sounds even they haven't internally or externally pip yet? I am talking to the egg and i say it's name. Name? Yes, name, i named it Goolagoo.... So i am figuring out if it is hearing the songs that i play right next to it, inside the incubator... The songs that i play on the egg are, Butterfly by smile.dk, You gotta lick it before we Kick it by 20 fingers and all of the other various classic songs, ranging from 60's to early 2000's. Disco songs and Soft rock songs...

Yes they do, and will start vocalizing in the egg as they approach hatching.

Once they internally pip they peep back and already know the sound of the Mommas voice.
