Corid dosage for sick chicks

[Momma 2 silkies]

I have 10 silkies and was told to get Corid to take care of their bloody poop and help them get better. I need to know how to dose them. Do I need to make a gallon of the water mixture of can I mix it daily as I water them? How much powder for a gallon and how much power for the 4 qt water container they drink from daily? Need to know fast, my babies were sick yesterday but couldn't get the powder until today. Please help me save my babies.

Good luck.

Thank you, I already got them started and some are starting to pick up already. I just hope I caught it in time, my favorite is the one I noticed sick, I really don't want to lose him now. Getting ready to go clean the brooder now, cleaning every day until they are better and then I plan to move them outside to their coop, waiting until after this heat passes. High heat and sick chicks isn't something I want to have to worry about with them being outside.
