Whenever I treat for cocci I make up the medicated water each morning, and then use it to make some wet mash before filling the water bowls. That way I know that the birds are getting the medication one way or another.
I agree with MrsBachbach to hold off putting ACV in the water whilst you are treating for cocci - it is acidic, and I don't know what the effect would be on the cocci medication, so it would be best to wait until after you have completed the treatment.
Have you tried putting a piece of polar fleece, a towel or an old soft toy in the brooder (preferably under or close to the heat lamp)? If the chicks are cold / scared then it will give them both extra warmth and some fluffy comfort. I know my chicks loved to cuddle into an old fleece top that I put in the brooder for them - they would find where the material was wrinkled and would snuggle down into it!
