Without a really long video of that "new quack" i cannot tell you what it is about. And i am pretty fluent in Duck by now…So in the past few days I’ve noticed the girls doing a new quack. Anytime I look in the dog houses with straw or go into the coop (looking for eggs that aren’t there) they all start up with this weird short quack. Makes me think of the kiddie carnival spaceship ridesbut they seem all fussy at me then I walk away and they stop... @Mimi13 or @WannaBeHillBilly do yours do this? Also, if they aren’t even touching the oyster shell is there a chance they may just not like it and I need to try a different brand?

The oyster-shells - don't be worried, they will know when they need those. Usually within one to two weeks after starting to lay, they will start consuming the extra calcium. It also helps to offer oyster shells to ducklings. (Yes, start screaming at me y'all!) Both times when my ducks had their own babies in the duck house, the younglings started to eat oyster shells, following mom's example when they were less than one week old. They all survived, even the drakelings.
