Cocci, can I add other stuff to water with corrid?many questions :(

[silkieaddictIN]

My chicks have cocci, one died today, she had bloody poo, fluffed feathers, lethargic, etc. I bought corid, and put it in water at noon. I bought Durvet Performance Poultry probiotics & electrolytes for poultry
....should I add this to the water now or in 5 days after corid trearment?

What's the best to clean coop and ground with?
I am buying sand for our coop, and I change bedding 3 x a day right now, plus sanitize.

All chicks seems ok, besides the one who died

Are there long term effects of corrid on eggs or egg production?
Any long term effects of cocci on health , egg prosuction, etc?

I plan to add DE to coop also, small amount in sand and a feeder of it.

They are also on medicated feed...I bought them at local sale barn, they were emaciated and dirty, I expected issues, but wanted to try.
