Hiya, and welcome to BYC! 
Not one to two cups of yogurt for three chicks. A couple of tablespoons is plenty.
I’d do the Corid though for all of them as it won’t hurt and might be the problem. Don’t give them any vitamins while on Corid
After you finish the Corid regiment, vitamin water every other day for a week or two would help them. Most of us use Poultry Cell.
Hopefully that one comes around! We’re glad you’re here!
