Evening for those down under 
You might try providing just the yolk with the salmon and make sure it has some chick grit. If their amino acids are out of wack it's difficult to make use of the energy in the feed. The yolk has a perfect balance of amino acids. If you can get it, I'd also try a bit of nutri drench straight to the beak or in the water.

@rjohns39 I have salmon! And hard boiled eggs!
