Hens eating my duck eggs

What is the protein percentage?
Different brand growers may have different levels.

Mine is 16% although different brands use different protein.

Just saw this, sorry. I know that feeding ACV reduces calcium absorption.

Fill up an egg with mustard and put it in the nesting box and they won’t eat your duck or chicken eggs anymore I’ve had to do this and it works

This didn’t work for my chickens. They ate the mustard egg, mustard and shell.
