16:8?
24:0?

It's a small deal.

Would they be happier with some rest?
Perhaps.

Bigger? Fatter? Another inch? Another gram?
Maybe.
Maybe not.

I did raise six 'lings at 24:0 alongside a half dozen at 16:8.
Since I personally found no significant advantage to 24:0, and I'm cheap, I use 16:8.

Same growth, same gender ratio, less expense.
A no-brainer for me.

Different strokes.
