Mealworms for 9 day old chicks?

Thanks, I've heard of Jenks Hatchery but don't know any real details about them. I can't figure out what them fully feathering out has to do with their immune system.

I am not a poultry professional. I give mine access to dirt shorty after hatch and have never seen any problems from that. Good luck!

And there's never been mortality or early illness ?
