How long can a chick with cocci go untreated for?

I was out for most of the day today. Got home at about 6pm and the chicks seemed fine. A few hours later (9-10pm) I went to clean their box and noticed a tiny bit of blood on a paper towel, then a sick looking chick.
I don't know for sure if it is coccidiosis but thought it was a high possibility. I don't have anything to treat it with and it is now 1am. Will it last until the morning when I can get some medication? and do I just assume that the others have it too seeing as they are all together?
I clean their box twice a day. They are eating normal chick starter. I put vitamins in their water at least once a day. And they are one week old.

I have not had to deal with it but from all that I have read, when it hits, it can kill quickly. I would get meds as soon as you can and treat all. If one has it, they all have it. Good luck!

That bird may not survive period. By the time they are showing bloody stools a lot of damage has been done. Treat them ASAP, but don't hold out any real hope of saving the most afflicted. Some straight Poly-Vi-Sol without iron may be helpful in treating them, especially for the really sick one.

Good luck.

You'll need to dose them with Corid (amprolium) asap. It can be found in the cattle section at a feed store. A temporary treatment from what I've read, buy some powdered milk and sprinkle the powder on their feed to eat it. It should help til you get the corid.

Well it's still alive. Pretty much the same as last night. It's just got to wait another few hours for the vet to open.
Ive had a good look and can't see anymore blood. The other chicks are looking the same, healthy, as last night.
