Coccidiosis - how long through treatment before no blood visible?

[Kiki]

I thought I'd give you an update on the ex batts!
Thankfully, they are all now doing very well. The blood in the poop became a little less but two of the hens were still very poorly, not eating and very lethargic. The vet felt that as they had had such a rough time with worms and coccidiosis the likelihood was they were suffering from a secondary infection. He gave me an antiobiotic Sulfadiazine/Trimethoprim to try. After 2 days there was a great improvement and after 5 days they were eating well again.
Happily they are now all starting to flourish in their new home, free ranging with their new friends and enjoying their new life! I'm over the moon that they recovered - thank you all once again for all your help.

Awesome! Good news.
